Google (NASDAQ: GOOG) wants to see if the attention span of its YouTube users can be stretched a bit. According to this Fortune article, YouTube seems to think that short clips might not necessarily be the backbone of long-term growth. Instead, longer videos might make the site more valuable. Why is this? Well, the article intimates that the founders of the site, Chad Hurley and Steve Chen, think there's a market out there that might want something more than simple, user-generated content that focuses on the banal side of life for about three minutes per clip.

I see the point here. Google wants to figure out, once and for all, the best way to monetize its YouTube investment. This isn't the easiest thing to do, since users of YouTube are, in theory, only interested in seeing short content as fast as possible. They don't want to be burdened by ads. But YouTube is betting that maybe, just maybe, by going against theory and putting on longer material of better quality, the eyeballs will become more intrigued and will perhaps be willing to view a greater quantity of videos. It all comes down to the quality of the content.
