A lot of entertainers have been using the Web increasingly to promote upcoming material, so it comes as no surprise that the Jonas Brothers have turned there aggressively to do a countdown for their latest music release.

The new album, which is inexplicably called “Lines, Vines and Trying Times,” is set to debut next week on June 16.

Thus, the pop trio have been doing a lot of online promotions, such a live Facebook Webcast on their fan page today at 5 pm PDT.

And they are also posting a lot of original online videos, especially at their YouTube channel.

Unfortunately, the digital hawking includes the one below, which is due to some fan request that has landed Joe Jonas in spike heels and a leotard, doing a bizarre dance interpretation of Beyoncé’s infectious and very viral music video, “Single Ladies (Put A Ring On It).”

After that video soared last fall, a lot of fans did their own versions, including a very funny spoof by Justin Timberlake, essentially doing the same gig as Jonas (except funny).

But, you be the judge.

Here are all three: Beyoncé in the original, TImberlake in the spoof (a bad version–sorry) and Joe Jonas in, well, it is hard to describe:

A billion dollar investment in digital technologies, struck between a handful of Hollywood studios and a consortium of big theater chains, got little notice earlier this week.

Under terms of the deal, the entertainment companies agreed to help defray the costs of rolling out more advanced digital technologies in 20,000 theaters, which will eventually lead to being able to see more movies using technologies like 3-D.

Even though there will be about two dozen 3-D movies released in the next few years–think Hannah Montana and the Jonas Brothers in concert popping out of screens–a very small number of theaters across the U.S. can handle the advanced technology 3-D requires.

Why? Well, it apparently costs about $70,000 to upgrade a screen. While studios are only paying a small fraction of that cost, one hopes they understand that upgrading theater facilities will be increasingly important in the years ahead.

Because while the gimmick of getting audiences to wear polarized lenses–yes, you still need them–3-D alone is probably not what will prompt most people to up their movie theater attendance (although 3-D movies do attract more people and command much higher prices).

But, even as digital technologies have exploded everywhere, the theater experience has changed in a negligible way over time.

While questions swirl around whether such upgrades pay off, there is no question it will be hard to know without some effort on behalf of the entertainment industry.

One might imagine a much more immersive theater experience or new ideas from filmmakers–I am not creative enough to come up with any good ones–to amplify a movie.

So we’ll just have to wait for Hollywood to come up with something–well beyond Miley Cyrus or Nick Jonas jumping right into the seats.
