Not sure its been in a golden age since cable TV changed the landscape. Now with streaming that are so many options to network programming. The quality of network programming is down to nothing. Find some hit and keep spinning off clones until they who thing tumbles down and now in the US with the move to ATSC3 over the air TV will all but disappear and will require at least a internet back channel to watch over the air programming due to the DRM being added.
Our local NBC has local news starting at 4am, basically repeating the same story's until the 7am network news. Network has a few minutes of news then a 3 hours of fulff they call news. then some infotainment show, then back to 2hr of local news, back to some dateline drama, then back to a 4pm to 7pm local news regurgitating the same stories. Now 1/2hr of network news, then infotainment, then from 8-11 you have some series from the network. then 1/2hr late news and then ingto overnight whatever programming. SO at best you get 3 hours of programming, that is if you like the shows in the 8-11 window and then after the "seasson" is over your in re-runs.
Hardly a golden age of TV...
