Yesterday, BoomTown went to Washington, D.C. to see lawyers from Microsoft (MSFT), Yahoo and Google face off in Senate hearings about the controversial search advertising outsourcing deal recently struck between Yahoo (YHOO) and Google (GOOG).

Titled “The Google-Yahoo Agreement and the Future of Internet Advertising,” the hearings were called by the Judiciary Committee’s Subcommittee on Antitrust, Competition Policy and Consumer Rights and chaired by Sen. Herb Kohl (D., Wis.).

As I expected, the hearings on the Yahoo agreement with Google (transcripts of testimonies here) to outsource some of its ad search business were a lot of show and not so much content.

There was also a hearing for the House’s Task Force on Competition Policy and Antitrust Laws, called “Competition on the Internet,” which featured the same trio of execs.

And here’s a video of BoomTown chatting up Google’s Chief Legal Officer David Drummond, Microsoft’s General Counsel Brad Smith and Michael Callahan, general counsel for Yahoo, right after the Senate hearings were over.

Today, BoomTown boards the Acela Express from New York’s Penn Station to D.C.’s Union Station to attend the Senate hearing on the Yahoo agreement with Google to outsource some of its ad search business.

Titled rather ominously, “The Google-Yahoo Agreement and the Future of Internet Advertising,” the Judiciary Committee’s Subcommittee on Antitrust, Competition Policy and Consumer Rights (eek!) will hear testimony at 10:30 a.m. at the Dirksen Senate Office Building from a passel of Internet reps, including those from Yahoo, Microsoft and Google.

It is chaired by Sen. Herbert Kohl (D., Wis.).

Will there be a lovely video of event? Indeed, there will be!

Added plus: I went to college and even worked on Capitol Hill, all before toiling at the Washington Post (Hey, Marcus!) for a dog’s age, so I know my way around the place.

And, as BoomTown readers might recall, I am not for the deal, mostly because it gives Google even more market power, even though the partnership is limited.

As I wrote:

As someone who has been a longtime critic of Microsoft’s (MSFT) historically thuggish tendencies, BoomTown finds it a little hard to believe that Yahoo and Google think that they can get away with any kind of significant search-ad outsourcing deal that would move the needle at Yahoo … .

And while it might be a long-cherished dream of Google’s to take over Yahoo search–and also get the chance to return to the scene of the crime, since Google got its first big push from doing Yahoo search, before Yahoo (YHOO) wised up too late–there is simply no way this will be allowed by regulators. Nor should it.

Still, you have to almost admire the chutzpah of the search giant in making this move, if the sheer and unadulterated arrogance of it wasn’t so distracting.

Because, while Google (GOOG) has almost none of the obvious menacing aggression that characterized Microsoft when it thoroughly dominated tech (although all those beach bikes on its campus inexplicably creep me out a little bit), the company still cannot be allowed to have a monopolistic share of the market.

It is bad for advertisers, it is bad for consumers, it is bad for innovation, no matter how well-intentioned Google is.”

So, you might imagine, I am looking forward to biting into this tasty piece of political theater!
