The death of the channel
TV only evolved the way it did because of the scarcity of VHF broadcast bandwidth. It was necessary to cram an entire nation's viewing into a small band of frequencies and a handful of channels. So there was an inevitable "rationing" of content: one (programme) for you, one for me, one for the children, one for the clever people, one for the food-fetishists, one for the sports-geeks - and so on.
Satellite TV eliminated that scarcity. In fact, with over 10,000 channels available int he UK from various satellites, the problem was more one of discovery than of rarity: which channel on which satellite is showing the football - with a commentary in my language? Which channel is showing the latest summer block-buster? Which 200-300 are showing Friends, or NCIS or whatever other american series?
But with box-sets (a piece of marketing genius: imagine being able to collect together a load of old repeats and get people to actually pay again to watch them?) and streaming and a small number of premium content providers, those problems are a thing of the past. The difficulty now is one of moderating your behaviour and having the self-discipline to put down the remote and walk away.
We should consider ourselves lucky that no channel is streaming Eastenders from end-to-end, all day every day.
