The Shallowing Slope of VOD Concurrency


Video-on-demand is on a huge growth curve. The average VOD library size is expected to jump from under 10 TB in 2008 to over 20 TB in 2009, and, according to Pike and Fisher stats I’ve seen referenced, on-demand viewing is projected to jump from 9% of all viewing last year to 38% of viewing by 2012. The net effect is that more VOD content is moving into the long tail. While it used to be that 20% of on-demand videos supported 80% of viewers, now that same 80% is accessing 50% of available content.

That’s a streaming challenge and a storage challenge, and it means cable networks have to get a lot more efficient in how they move video out to on-demand subscribers. They can’t just make 20% of content available at the edge of their networks and assume few people will access anything else. But they also can’t store everything at every edge server because of scaling issues.
