As you've probably heard by now, Google went ahead and made YouTube an honest woman by dropping $1.65 billion on the online video site. What sorts of changes can we expect now that YouTube has the richest of sugar daddies? Well, for one, Google is gonna want to start making money with YouTube, something that hasn't been done yet. Ads becoming embedded in the millions of free videos on the site is the most likely scenario, with YouTube co-founder Chad Hurley telling The New York Times that he would consider implementing the 15-second "preroll" ads that he's opposed in the past. The ads would play at the beginning of every video. In addition to advertising, it's probable that a lot of the copyrighted material now all over the site will be much harder to come by. Currently it's really easy to watch everything from Jon Stewart's latest digs at the president to last night's episode of South Park, but copyright holders aren't too happy about the fact that users can watch their content for free. While Google has a lot of money to toss around, it doesn't want to get sued by a giant media company. YouTube is reportedly at work on software that would automatically detect copyrighted material and pull it down, something that would seriously change the nature of the site. Of course, time will tell what Google has in mind for its new acquisition, but in any case it should be interesting to see what happens when two of the biggest and most buzzed-about sites on the Web join forces. Stay tuned.
