Ya, you were just being jingoistic. Not everything is racism, some is just ignorant nationalism.

Money and really population. 103 million Americans watched the last episode of MASH, at the same time the population of the UK was 56 million people.

Outside the filler part, this is one of the more insightful posts. Few people seem to acknowledge America was the only first world country untouched by WW2, we actually turned a nice profit and had manufacturing rolling to extend the profitability while Europe rebuilt. This is the same time frame where tv culture began to develop.

It's also why every UK actor who can do a passable American accent is in America working. You have to search hard to find American actors working in UK tv.

You haven't seen enough UK TV. There are plenty of shows that run endlessly. I just finished 11 series of Never the Twain.

Or, the more shit you throw at a wall the more sticks.

The syndication 100 episode marker wasn't it though. Networks originally didn't want to let their shows be re-run at all as they thought it would decrease demand for the new stuff. Syndication was a later development.

This isn't really true. From the 1970s to 1990s both Countries had 3 TV stations producing the bulk of the content. BBC, BBC2 and whatever ITV was in the UK and NBC, CBS and ABC in USA.
