As an advocate for online television and video I also frequently have to remind clients and enthusiasts that usage is still relatively marginal compared to the traditional broadcast media business. The undoubtedly successful BBC iPlayer reaches over four million online video viewers a week, but the highest online audiences for individual shows are still in the hundreds of thousands and many more receive far fewer requests. Individual episodes of Channel 4 shows on YouTube are getting literally dozens of views a week. So it’s important to keep a sense of perspective. Next week the Online TV and Video Summit in London will be discussing the challenges and opportunities of online distribution. I’ll be chairing the first day and I hope to see many of you there.
