Here is my March article for Mediatel’s Newsline, for whom I write an opinion column. It is normally focussed on media research issues – this one is more technology focused, but for a reason. It ties together a few thoughts going round in my head with some conversations with experts about how the Internet actually works in practice when it comes to watching video.

In short, TV is a mass linear medium – despite all the catch up services available to us, we love to watch linear broadcasts at the same time as everyone else and the public Internet just isn’t designed to cope with even a modest amount of what is called ‘multicast’.  As usage grows even non-linear catch up services are groaning under the strain. Anyway for more on this here’s the article.
