YouTube could be a huge catalyst for unlocking Google's (NASDAQ:GOOGL) Chromecast opportunity, Fool contributor Tim Beyers says in the following video.

Content is key to Chromecast's success and Pandora is the latest to join the ranks. A nice win, Tim says, but not as important as making YouTube a genuine alternative to cable or downloadable alternatives. Investing in new forms such as documentary shorts or even low-budget feature films that otherwise wouldn't enjoy wide release could get more viewers tuning in to view ads.

Of course, Google doesn't necessarily need Chromecast in order to boost YouTube viewership. But having it makes it easier to access web video, and there's no bigger destination for web-based video programming than YouTube. Google needs to bolster both products in order to make a serious run at disrupting traditional TV, Tim says.
