"Quality Revolution continues, grainy, low-res amateur content is becoming a less compelling experience on the Web, rendering the YouTube Inc. model obsolete. Here's the big problem with mass-market UGC sites: While online content distribution costs are coming down, they are not coming down nearly as fast as the volume of content is rising. At the same time, advertising monetization is only covering a small portion of the inventory, and the recession has slowed its growth. Imagine a store where you stock thousands of items, but only 5 percent of them are ever sold.
That's YouTube. If you are a least common denominator (LCD), mass-market, low-quality, or UGC site with a low CPM (cost per thousand) advertising-based business model, you're pretty much hosed. Credit Suisse analyst Spencer Wang hit the nail on the head, with a recent report estimating how big this problem is. Wang ran some calculations on the YouTube situation and concluded the site might hemorrhage as much as a half a billion dollars in 2009. That's a lot of money, even for Google, which owns the site. You might be a little better off if you are a higher-quality content site, such as a Hulu LLC , or even better yet, a high-quality video site with a niche audience or even a special vertical, where you can charge your advertisers a high CPM. But even these guys are struggling. Mostly it's because the consumption of video is exploding, so they are also struggling with bandwidth costs. Yes, the costs are decreasing, but not as fast as consumption is increasing. High-definition (HD) video compounds the problem.
As we move to an HD world, the massive amounts of bandwidth that will be consumed is tremendous. This is one of the problems that Mark Cuban has been riffing on -- with the economies of the Internet, it's very hard to pay for this explosion of bandwidth-chowing content, unless you get the consumer to pay for some of it. Mio Babic, the CEO of iStreamPlanet Co. says there doesn't seem to be any way that a low-CPM UGC site like YouTube will make money. Ever..."
