The Guitar Hero 'bike' video is featured in this, which was done by agency Droga5 as a viral video. There's a running debate over authenticity, as not only the origins of the video become a topic, but also seeding practices are now commonly known. That awareness is often reflected in comments like the one that appeared on the GH vid: "What's up, viral marketing douchebags?"

Vids can be HD, and play full screen. Few video sites offer a truly compelling reason to switch from YouTube, but HD support is big if quality is a concern.

Despite the downward revision, there's still enormous upside growth.

Quote: “Even as video becomes the great growth area for internet advertising, there’s a major disconnect between the amount of time people spend with short-form video, especially user-generated, and the ad dollars that accompany such video content,” said eMarketer senior analyst David Hallerman.

“However, as media companies change their business model, putting more and more professionally created video content online, the audience - and related ad dollars - will increase dramatically.”

They said 'Playboy shedding', hehe. The porn industry has often been cited as a trend leader in online commerce. In this case, I certainly think they're right. For the same reason records became too expensive to stamp out, and CD sales are tanking in favor of downloads, DVDs can't be far behind. With the ability to download HD quality content, and (knock on wood), broadband speeds destined to rise, this only makes sense.

On a related note, the numbers from Radiohead's little experiment are in. Score! Mashable has a good rundown:

Thought this was very cool that a business site like Forbes would put out an office pranks site. Definitely adds accessibility to the brand.
