No TV on the web for now

I often find myself in a discussion about how we are all going to watch TV 'on the web' in the near future. Look at YouTube people say. And altough that model might sound really promising and obvious, they don't realize the effort required to make it all happen. Robert Arn tries to explain it over at VentureBeat. And no, P2P is not the answer...

"Let’s look at the real data volumes and associated costs behind the belief network. Some 111 million U.S. households have their TV sets on an average of 8.5 hours a day, according to the Television Bureau of Advertising and Nielsen Media Research. This represents a data volume of about 318,000 TeraBytes per day, or 1590 times the data volume of YouTube. Who is going to deliver it? Akamai? No, and here’s why: Akamai has roughly 300 Gb/s bandwidth in its network today. Building that network cost about $329 Million in raw asset and facility purchases, let’s say about $1Million per Gb/s of bandwidth. To deliver the volume of data just described would take about 83,000 Gb/s bandwidth. That’s $83 billion of capital cost in the Akamai model."
