Incredibly, this is the seventh year of the D: All Things Digital conference.

We feel very lucky to get here, especially in the midst of what our own site’s Digital Daily scribe, John Paczkowski, has so perfectly dubbed the “econalypse.”

Ironically, Walt Mossberg and I planned to launch the very first conference in the middle of the last major downturn for tech, in 2001. But, in the carnage of the Web 1.0 meltdown, we actually held off for two years, with our first D gathering taking place in 2003.

It’s been a real winning streak since then for D, due in large part to our great speakers–such as Microsoft (MSFT) icon Bill Gates and Apple (AAPL) legend Steve Jobs.

Both have been onstage many times over the years, including a historic interview the pair of tech titans did together in 2007 at D5.

Other amazing speakers have included: Howard Stringer of Sony (SNE), Barry Diller of InterActiveCorp (IACI), legendary director George Lucas, Time Warner (TWX) CEO Jeff Bewkes, Jeff Bezos of Amazon (AMZN), former eBay (EBAY) CEO Meg Whitman, News Corp. (NWS) head Rupert Murdoch, Microsoft head Steve Ballmer, Walt Disney (DIS) honcho Bob Iger, Bobby Kotick of Activision Blizzard (ATVI), CBS (CBS) CEO Les Moonves, Democratic and Republican pols like former Vice President Al Gore and Sen. John McCain, all the leadership of Google (GOOG) and many, many more.

We have had a lot of great moments onstage with all these tech and media players over the years, to be sure, with interviews ranging from the funny to the sublime to the truly disastrous.

But, like the digital industry and the innovation our conference focuses on, we also like to lean forward to try to figure out what the Next Big Thing is around the corner, whether it comes from Silicon Valley or not.

That’s why we’re kicking off our conference on May 26 with two of the founders of Twitter–Biz Stone and Evan Williams–who are riding high on tech’s latest hot thing, which might turn out to be either a rocket ship or a shooting star.

They’ll be followed up over the next two days by a plethora of interesting players, from the leaders of several major mobile companies to content execs hit hard by fast-moving digital forces to a new Internet leader like Yahoo (YHOO) CEO Carol Bartz, who is trying to turn around one of the Web’s great icons from its more recent lackluster path.

And, as we always do, we will be featuring a spate of demos too, trying to see if we can unearth that next next thing.

In the past, the D stage has seen the debut of start-up products like Sling Media’s Slingbox, Aliph’s Jawbone and Pure Digital’s Flip, all of which have gone onto glory. And also some, like Palm’s Foleo, which did not.

While not everyone can attend D, our crack staff is committed to bringing all the action from this year’s conference to readers of the All Things Digital site via up-to-the-minute blogs, photos, videos, tweets, digs and more. We’ll also, as soon as we can, post the videos of each of the onstage sessions, in their entirety.

Until it all kicks off, here is the list of speakers, below, in alphabetical order, who will be appearing at 2009’s D7 conference:

Irving Azoff | CEO of Ticketmaster Entertainment (TKTM)

In Web years, BoomTown is now officially 143 years old.

Why? Well, I was the one who got to write the big Page One piece in The Wall Street Journal after GeoCities was sold to Yahoo in January of 1999 for $5 billion in stock.

GeoCities was, in its way, the Facebook of its time.

But instead of “friends,” its users were “homesteaders,” since the Web then was a place to be pioneered and settled.

As Cher so eloquently sings: Those were the days my friend, we thought they’d never end.

Except they did. Yahoo (YHOO) announced yesterday that it was closing the GeoCities unit down, part of new CEO Carol Bartz’s war against useless assets at the troubled company.

But a full decade ago, the Yahoo-GeoCities transaction was a big, big deal, struck at the peak of the Web 1.0 bubble.

The move shook up the then-Internet landscape, in which Yahoo was the undisputed king.

The sector then had begun to rapidly consolidate, as stronger players snapped up weaker ones in a race for market share.

The Yahoo-GeoCities deal closely followed another deal in which At Home, a high-speed Internet access service, bought search and directory service Excite for stock valued at $6.7 billion. In another key deal at the time, then-independent America Online agreed to buy Netscape Communications for stock then worth $4.2 billion.

Of those then-dominant Web companies, only Yahoo and AOL–now a troubled unit of Time Warner (TWX)–survive relatively intact.

And, what exactly did Yahoo get for its giant payment back then? A money-losing, low-revenue company with a whole lot of users.

At the time of the purchase, the publicly-traded Marina Del Rey, Calif., company had reported that fourth-quarter sales increased to $7.5 million from $1.7 million a year earlier. But the company’s loss had also swelled, to $8.4 million from $3 million, in the year-earlier period.

Sound familiar to some current Web 2.0 stories? I thought so.

Another weird irony: One of GeoCities major investors was a venture firm called Flatiron Partners, whose principal, Jerry Colonna, was on the board.

And who was Colonna’s parter? Well, Fred Wilson, who has a different firm now called Union Square Ventures and is–wait for it–one the the major investors in the 2009 hotsy-totsy start-up, Twitter.

(You can read Wilson’s terrific take from the VC perspective of the GeoCities experience here.)

In other words, the more things change… Well, actually, they don’t change.

So, if you want to take an instructive trip down memory lane, here is my piece below, which appeared in The Wall Street Journal on Jan. 29, 1999:

Those Who Tied Fortune to GeoCities Yell Yahoo! All the Way to the Bank

By KARA SWISHER | Staff Reporter of THE WALL STREET JOURNAL

Last spring, Thomas R. Evans was nervous about leaving his longtime job at the top of a powerful Manhattan media company for an Internet start-up near the beaches of Southern California. So he talked to his boss, real-estate and publishing tycoon Mort Zuckerman.

“I was wondering if this whole Internet thing was real and sustainable,” says Mr. Evans, then publisher of the Atlantic Monthly and U.S. News & World Report. “I wanted his blessing in a way.”

Virtual Payoff

Mr. Evans got Mr. Zuckerman’s nod–and a lot more. You know the drill by now (though it may not be getting any easier to hear). He became chief executive officer of GeoCities , an electronic casbah of about 3.5 million Web sites, and helped lead its initial public offering last summer. Then Thursday, Yahoo! Inc. agreed to buy the young company for about $5 billion in stock. It means the value of Mr. Evans’s stock options soared by 65% Thursday to a dizzying $200 million.

Yahoo! Agrees to Buy GeoCities in $5 Billion Stock Transaction

That’s some kind of money for nine months’ work. After you’re done banging your head on a wall, consider that members of the new financial elite in Silicon Valley are being created in less time than it takes for a kid to finish his first-grade year. That puts oil, real estate and finance magnates to shame. Mr. Zuckerman, for example, spent a lifetime building his $1 billion financial empire.

Asked how he was doing Thursday, Mr. Zuckerman says: “Not as good as Tom Evans.”

Mr. Evans, who commutes between GeoCities’ Marina Del Rey, Calif., headquarters and his home in New Canaan, Conn., is quick to point out the ephemeral nature of his wealth. He must wait six years for his options to be fully vested. And his net worth could evaporate if Yahoo’s highflying stock sinks.

“It does not seem real, because it is not real, because this is based on the long term and is dependent on where this whole industry is going,” says Mr. Evans, 44 years old. “Anyone coming into this industry assumes a certain amount of risk because no one really knows how it is all going to turn out.”

Litany of Lucre

It has turned out well so far for the new moguls at GeoCities. According to public filings the company made last summer, the biggest individual winner is co-founder and Chairman David Bohnett, 42, who owns about three million shares outright, now worth $367 million, based on Yahoo’s closing price Thursday. Mr. Bohnett insists he is overlooking that bit of extra money. “I do not see this as a financial event,” he says. “And we did not start this company with money in mind.”

Chief Technical Officer John Rezner, 35, who worked nine years for aerospace company McDonnell Douglas Corp. before co-founding GeoCities, holds 827,000 shares worth $103 million.

The management team that came in with Mr. Evans last year–taking over from Mr. Bohnett to help with the IPO–is also well-situated. Chief Financial Officer Stephen Hansen, 42, who formerly held the same position at Universal Studios Hollywood, has options for about 600,000 shares of stock, which would be worth $74.7 million at current prices. Michael Barrett, 36, advertising vice president and former online executive with Walt Disney Co., has options for 280,000 shares, worth about $34.9 million.

There are, of course, all kinds of gnashing of teeth over whether the Internet entrepreneurs deserve such riches. But obtaining great wealth through luck or artful maneuvering is nothing new in American business history. Take the stock manipulators of the 1890s and the leveraged-buyout artists of the 1980s. It may be some consolation that GeoCities’ founders can claim that they developed something that is used by many people. In its December Web-traffic report, research firm Media Metrix says the “GeoCities.com” Web site ranked third, behind America Online Inc. and Yahoo, with nearly 19 million different visitors.

Mr. Bohnett says the company was born from a “passion for giving people a chance to speak up.” Founded in 1994, GeoCities was one of the first Web-based communities, where users post individualized sites to express themselves.

Dubbed “homesteaders,” these customers create the bulk of the content on GeoCities. Their Web pages are organized into “neighborhoods” of personal interests and hobbies, such as personal finance or motorcycles, and monitored by a network of volunteers.

“My goal was to stake out a broader territory and create a community of interests, just in the same way Yahoo was helping people find their way around the Web,” says Mr. Bohnett, who led the company in a variety of top jobs, including chief financial officer, CEO and president. “Then we were going to monetize that base of users as the business model emerged.”

That model for profitability hasn’t yet arrived, in part because the company spends heavily to increase its market share. Thursday, it announced a net loss for last year of $18.2 million on revenue of $18.4 million.

Mr. Evans, a dark-haired man with a preppy demeanor and razor wit, has plenty of experience building businesses. He worked his way up in Mr. Zuckerman’s organization from sales and advertising jobs, and eventually served as president and publisher of several magazines.

After being approached several times about new-media positions, Mr. Evans says he decided to jump to GeoCities when the importance of the Internet became clear to him. “I think that by the time I really took a look at it, the whole sector had matured and gotten really interesting for those of us in the traditional media companies,” he says.

While Mr. Evans is loath to discuss the valuations of Internet companies, his former boss Mr. Zuckerman doesn’t dodge the opportunity to be philosophical about Web mania.

“It’s like they said in high school: ‘Boys will be boys and girls will be girls,’” Mr. Zuckerman says. “I don’t want to change anything, I just want to get in on it.”

As soon as he got his new job last week, new AOL Chairman and CEO Tim Armstrong sent out a rather hopeful email to the troops–his first communication as the latest leader of the ragtag online service.

“I’m really looking forward to seeing you and would love to hear your thoughts and suggestions,” wrote the former Google (GOOG) exec Friday (who alarmingly kind of resembles this Elvis image), “on how to make AOL and its sister properties the most powerful brands on the Internet.”

Well, one can hope!

To goose that dream, although he still does not officially start in the job until April 7, Armstrong is also addressing all the troops tomorrow at 11 am EST and has chosen to do so from, of all places, AOL’s old center of power in Dulles, Virginia.

AOL staffers I spoke to also hope most of all that Armstrong will quickly and transparently lay out plans for a spin-out of the Time Warner (TWX) online unit from the media conglomerate, where it has languished for years.

“Armstrong would not have taken the job if the plans for a spin out of AOL were not in place and it’s in everyone’s interests to signal that it’s a go right away,” said one source close to the situation. “The only catch is the poor economy, but even that should not prevent Time Warner from doing what’s right to finally fix AOL.”

And sources said Armstrong could further up the ante tomorrow and help raise the layoff-weary morale by having some former AOL execs from its glory days as the top online player in person at the event.

Several sources said one exec most likely to make an appearance is Ted Leonsis (pictured here), one of AOL’s most colorful top early execs and a longtime inspirational figure within its ranks.

Unlike most AOL execs from those days, many of whom were eventually run out on a rail, Leonsis also stayed on through its disastrous merger with Time Warner and beyond.

But, like all of the Dulles complex–which was once the bustling worldwide HQ for AOL–Leonsis finally left the company, after a falling out with the management regime that Armstrong just hipchecked out of power. He is now AOL’s vice chairman emeritus.

Both CEO Randy Falco and President Ron Grant moved AOL’s locus largely to New York, and minimized the staff and influence at Dulles, where most of AOL’s products have been made since its origins in the early 1990s.

“It’s a smart move to go to [the Dulles staff] directly first…the last regime pretty much shut them out…and that created bitterness, when we need to be unified,” wrote one AOL insider to me in an email.

(Sidenote: As the AOL beat reporter at the Washington Post back then, I actually went with then-PR head Jean Case to look over what became the Dulles facility, to see if it would be a good place to expand to; previously, AOL was located in nearby Vienna, behind a car dealership.)

A Leonsis visit at AOL will be like old home week, although some are hoping too that former AOL CEO Steve Case could also make an appearance. He and Leonsis still make online investments together.

But that might still be deeply controversial within Time Warner, where Case and also former Time Warner CEO Jerry Levin are widely blamed for situation that the company found itself in when the Web 1.0 bubble burst and AOL’s once vaunted valuation collapsed.

Although Case and Time Warner CEO Jeff Bewkes have since moved on, bygones have not been bygones within Time Warner.

And, while it is often denied by top execs, AOL has suffered because of ill-hidden grudges, which have partly prevented it from being revived, even as other Internet giants have been born in the interim.

Ironically, many of the current crop of shooting stars owe a lot to the pioneering and innovative AOL products, including: its AIM and ICQ instant messaging services, which echo an early version of Twitter; the “Buddy List,” which was all about friending; and its deep social networking roots, with chat rooms and profiles that were the Facebook of its day.

The question for Armstrong is: Can AOL go home again?

Recently, BoomTown had a lovely lunch with PBS new media blogger Mark Glaser (pictured here).

Glaser is a longtime free-lance journalist whom I first noticed when he wrote a weekly column for the USC Annenberg School of Communication’s Online Journalism Review, post-Web 1.0 bubble, as well as for the most excellent “Media Grok” daily email newsletter for the now-defunct Industry Standard back in the midst of the froth.

Glaser was always able to cut through that with a clear-headed tone–while maintaining a respect for what was good about traditional journalism, as well as an excitement about the possibilities of new media.

His MediaShift site for PBS has recently gotten much beefed up, with interesting pieces about a range of digital media topics, from a cool map-timeline combo from the Washington Post to a new business venture called the Printed Blog to, of course, the impact of social media on journalism.

(There is also an interesting closely linked site called “Idea Lab,” which is a group blog about reinventing community news in the digital age.)

Glaser writes on the MediaShift blog about once a week and has about a dozen contributors.

A recent post–and thank goodness for some counter-programming in the blogosphere–was titled: “Warning: Dependence on Facebook, Twitter Could Be Hazardous to Your Business.”

Here’s my video interview with him, on a range of issues facing the media in the interactive world (apparently, journalists don’t know everything!):

It was jokingly called the “Millionaires’ Dinner,” but I renamed it the “Billionaires’ Dinner.”

That was due to the frothy fortunes that had been made at the time by the Internet pioneers, from Amazon to AOL to eBay. Get it?!?

Well, despite the economic meltdown, there were still a lot of billionaires in attendance at Brockman’s most recent dinner last Thursday in Long Beach. But he recounted to me that the proceedings were a lot more focused on the serious times we are in, as was the whole digerati-packed conference held last week.

Indeed, Brockman now calls the event the “Edge Dinner,” after his lively Edge Web site, where he presides over a variety of eclectic online debates and discussions (in January, for example, the topic was: “DOES THE EMPIRICAL NATURE OF SCIENCE CONTRADICT THE REVELATORY NATURE OF FAITH?”).

Since I managed to miss the fete entirely (embarrassing confession: I fell dead asleep at 7 p.m. and did not wake until the next morning) and could not chronicle it, Brockman allowed me to post some photos from the event taken by him and by former Microsoft research guru and current intellectual property mogul Nathan Myhrvold.

Here are some, and you can see the rest here (click on the images to make them larger):

Google co-founder Larry Page and Applied Minds’ Danny Hillis

Former AOL kingpin and Revolution Health’s Steve Case and Jean Case, Case Foundation

Twitter CEO Evan Williams and Neoteny’s Joi Ito

Amazon Founder and CEO Jeff Bezos

Microsoft Co-founder Bill Gates and DEKA’s Dean Kamen

New Media Nabobs Tim O’Reilly and Arianna Huffington

It looks like Carol Bartz will be taking on the thankless role as new Yahoo CEO.

Sources close to the situation told BoomTown–which had first named the former Autodesk CEO the top pick last week–that Bartz (pictured here) has been approved for the job by the Yahoo board and has accepted it.

The Wall Street Journal is also reporting the move.

The pick is one of the safest Yahoo (YHOO) could have made, which is typical for it, choosing an experienced and strong public company CEO, but one without a lot of experience in advertising or the Web 2.0 Internet.

Sources close to the CEO search said that the Sunnyvale, Calif.-based company’s headhunter, Heidrick & Struggles, has told many that Yahoo would also be looking for a strong No. 2 with more Internet and product experience if a CEO with less online background was selected.

Candidates for that position are numerous.

That job is not likely to fall to its current incumbent, Yahoo President Sue Decker, although Bartz could choose to keep Decker, given her experience and depth of knowledge about Yahoo.

But it could be a little odd, too, if Decker stays, since she was also vying for the CEO job and was one of the top internal candidates.

But sources close to the Yahoo board said that many inside and outside the company would have reacted badly to a Decker appointment as CEO, given that she has been No. 2 to outgoing Yahoo CEO and Co-founder Jerry Yang.

The pair have presided over a decline in Yahoo’s business and an even deeper one of its stock.

Sources who have spoken to Decker said it is more likely she will leave the company, and had stayed this long out of loyalty to Yang.

Most controversially, some are concerned about Bartz’s possible closeness to Decker and Yang–Bartz serves on the Cisco (CSCO) board with Yang and the Intel (INTC) board with Decker–seeing the choice as an attempt by Yang to stay in power at Yahoo.

Yahoo’s board has also gotten a lot more rebuffs from outside execs than expected for the top spot, because of its major challenges. While rich in assets and online traffic, the company has suffered over the last year from a range of internal and external troubles.

In a reaction piece to the possibility of making Bartz the CEO of Yahoo I posted last week, the reaction was mixed, with some lauding it as an important move to steady the long troubled company, while others called it problematic for the Yahoo leader not to have a deep Web background.

One thing is sure: Bartz does know tech, unlike former CEO Terry Semel, who hailed from Hollywood. And she also knows how to run a company like clockwork, unlike Yang, who–while inspirational–has had a rocky tenure and has been considered weak in execution.

With an upcoming fourth-quarter results report on Jan. 27 likely to be a disaster, Bartz will have a lot on her plate, including working out a much expected search partnership with Microsoft (MSFT) and deciding what to do about the constipated deal to buy Time Warner (TWX) online unit AOL.

And, oh yes, fix Yahoo’s troubled graphical ad business and weak morale!

Early investor response to Bartz has been muted, at best, despite her solid credentials.

Bartz, 60, is certainly an experienced and very well-regarded tech exec, with the talent to turn things around. She served as chairman, president and CEO for 14 years at the San Rafael, Calif.-based Autodesk, which makes computer-aided design software for engineers.

While there, Bartz presided over huge growth at Autodesk (ADSK), stepping down in April of 2006 to spend more time with her family, and has since served as its executive chairman.

She also put in stints at other big tech companies, including Sun Microsystems (JAVA), Digital Equipment Corporation and 3M (MMM).

According to her resume on Autodesk’s Web site, Bartz holds an honors degree in computer science from the University of Wisconsin.

Bartz is also on the boards of a blue chip list of tech companies and organizations, including Intel, Cisco Systems, NetApp (NTAP), and the Foundation for the National Medals of Science and Technology.

She is also exactly the kind of serious, seasoned public company CEO with tech experience whom Yahoo’s board has told investors and others it is looking for, with skills to pull off mergers and think strategically.

But Bartz also was in charge of a more old-school kind of tech company and has less experience in the faster-moving Web environment that prevails now.

Although she toughed it out successfully, Bartz underwent difficult times during the Web 1.0 era, in fact, when investors were worried about Autodesk’s prospects in the online era.

Most critically, Bartz also has less advertising experience, which is Yahoo’s principal business.

In addition, Autodesk is half the size of Yahoo.

Nonetheless, she is well-liked in the tech community and has ties to key companies Yahoo must deal with, including Microsoft.

How did BoomTown forget former Autodesk exec Carol Bartz for Yahoo CEO?

Yahoo certainly hasn’t. According to several sources familiar with the Yahoo (YHOO) search for a new leader to replace Co-founder Jerry Yang, the company is looking hard at the longtime and high-profile Silicon Valley executive (pictured here).

Many I have spoken to inside and outside of Yahoo with knowledge of situation said the company is winnowing down its list to a few internal and external candidates and Bartz is a favorite.

While some speculate that Yahoo could announce a candidate sooner than later, it’s long past when Yahoo Chairman Roy Bostock promised some big investors a new and serious leader would be in place.

Some sources close to the board still think Yahoo could still end up opting for one of its own.

If so, the leading choice is most likely board member John Chapple, former Nextel CEO, although sources say he does not want the post now, preferring an outsider for Yahoo CEO. The other board member mentioned is Maggie Wilderotter, a former Microsoft exec.

Whoever gets the job needs to move quickly on a range of actions needed–from deciding the strategy with regard to a search deal with Microsoft (MSFT) to determining whether a long-running merger deal with Time Warner (TWX) online unit AOL should happen.

So far, Yahoo’s board has also gotten a lot more rebuffs from outside execs than expected for the top spot.

This is no surprise, due to the highly difficult task of turning the company around. While rich in assets and online traffic, Yahoo has suffered over the last year from a range of internal and external troubles.

Bartz is certainly an experienced and very well-regarded tech exec, with the talent to turn things around. She served as chairman, president and CEO for 14 years at the San Rafael, Calif.-based company that makes design software.

While there, Bartz presided over huge growth at Autodesk (ADSK), stepping down in April of 2006, and has since served as its executive chairman.

She also put in stints at other big tech companies, including Sun Microsystems (JAVA), Digital Equipment Corporation and 3M (MMM).

More interestingly, Bartz is also on the boards of a blue chip list of companies and organizations, including Intel (INTC), Cisco Systems (CSCO), NetApp (NTAP), and the Foundation for the National Medals of Science and Technology.

Yang is also on the board of Cisco, and Yahoo President Sue Decker is on Intel’s, so Bartz is a well known quantity to Yahoo.

She is also exactly the kind of serious, seasoned public company CEO with tech experience whom Yahoo’s board has told investors and others it is looking for, with skills to pull off mergers and think strategically.

But Bartz also was in charge of a more old-school kind of tech company, and has less experience in the faster-moving Web environment that prevails now.

Although she toughed it out successfully, Bartz underwent difficult times during the Web 1.0 era, in fact, when investors were worried about Autodesk’s prospects in the online era.

Still, Bartz also has less advertising experience, which is Yahoo’s principal business.

Nonetheless, she is well-liked in the tech community and has ties to key companies Yahoo must deal with, including Microsoft.

Whether Bartz herself is interested in taking over a massive overhaul like Yahoo is unclear. I reached out to her for a comment, but have not heard back yet.

According to her resume on Autodesk’s Web site, Bartz holds an honors degree in computer science from the University of Wisconsin.
