"AndroidなどのオープンソースプロジェクトはGoogleに直接的に収益をもたらさないが、同社に収益をもたらす場所にユーザーを導くと言っても差し支えないだろう。このことはGoogleを理解する上での基本だ"

The San Jose Mercury News, among others, is reporting that Google's YouTube will begin checking content for copyrights, specifically in a test with Disney and Time Warner's content. They finally admitted they are using Audible Magic's clever system for checking copyrighted music, which the Merc reported earlier but Google wouldn't confirm. Now Google is asking copyright holders to send them copies of videos to check against. Mark Cuban, ever the copyright defender and YouTube attacker, cried foul at that one. Now I'll tell you what's really happening here (in my analyst's opinion).

Is YouTube worth $1.6B? You betcha. That’s 4 cents per video stream ($1.6B divided by 100 million daily views * 365 days) and it’s still growing. Another way to think of it is that YouTube has roughly 50 million users (35M in the US according to Nielsen NetRatings, and probably another 15M worldwide) which comes out to $32 per user. It’s high, but it’s also reasonable.
