If you say that American TV channels are obsessed with fitting their programmes to a 30 minute grid then is that purely cultural or does it have any roots from the depths of time?
American cities are similarly "organised", cookie-cutter and all similar-looking too: their cities are full of grids, as their cul-de-sac suburbia is.. well, their TV schedules remind me a bit of that (actually, their TV in general)
I don't think it's something about mentality: more something about how things evolved, for some reasons
What is the reason why most programmes on US TV channels start on the hour or the half hour?
The more variable starting times for programmes on British terrestrial TV channels is the main reason why Video Plus was based on a different algorithm from VCR Plus used in the US.
Simply because it’s easier to remember for a viewer. My TiVo has been recording a block of ER on POP and despite it being originally broadcast in an hour format with roughly 43 minutes of content they added more ad time so the entire episode takes up about 70 minutes. The length of the episode causes odd start times like one was 6:17 PM. I know I certainly wouldn’t remember to tune in with that start time.
There’s the added benefit that you can change the channel at the end of a program without missing parts of the episode.
But "6:17" is an extreme example: most channels round the times in a 5 minutes basis, except children channels (as I showed before), as a loophole against EU legislation
About that: thanks to the new COSTA legislation, which tells you a kids programme has to be longer than 30 mins in order to have an ad break (instead of being exactly 30 mins), kids channels now look like a mess: not so much the ones who do 31 mins+ 29 mins, but the likes of Disney Channel, which have a "31 minutes" based schedule (14:01, 14:32, 15:03 etc.)
