Can't speak for the US but here in the UK broadcast is as popular as ever. The same amount of people watch broadcast TV and last year the average amount of time actually increased. 80% goes to the networks and their digital spin offs, the rest to cable and digital. Then of course online catch up via iPlayer, ITV Player, 4oD etc. are owned and operated by the networks themselves. But services like Netflix are add ons to TV rather than replacements, for the most part.
But I guess our TV environments are quite different. I get 150 channels and a DVR without subscription.
