I think now that Big Bang Theory is done we can close out the era of television, roughly 1950-1970. By this I mean 'Network Television', not 'anything that can show up on your screen'
And, as is it with media, we can look back with more clarity now that its influence wanes. It created its own memes and content suited towards it:
The Sitcom
The Drama (Westerns, Cop Shows, Medical Dramas)
The MiniSeries
Network News (not Cable News)
Sports (McLuhan talked about TV and Sports a lot, such as the 'instant replay')
....
The topic within the topic: What are the best and notable shows from the different eras that you watched ?
1950s - "Golden Age" - Playhouse 90, and high art on television; The Twilight Zone, The Honeymooners, Jack Benny (more of a radio guy but I love him)
1960s - Dick Van Dyke Show, Andy Griffith Show, Laugh-In, Fantasy Sitcoms (Bewitched, My Favourite Martian, I dream of Jeannie), Variety Shows, Hanna Barbara Cartoons, Get Smart, Youth-Oriented Music Shows (Shindig), Network News
1970s - Mary Tyler Moore & Spinoffs, Norman Lear shows, Sesame Street and the CTW, Saturday Night Live and The Midnight Special, Monday Night Football
1980s - NBC's "quality" comedies, the miniseries, Night Time Soaps
1990s - Seinfeld, The Simpsons, FOX arrives
2000s to present - the end; reality TV; end of the dominant network anchors; the last shows - 2 1/2 men, Big Bang Theory
Separate category: Daytime: Game Shows, Soap Operas and Talk Shows, Programming for Kids and Teens

What we aren't realizing today, so much, is that the end of this era means the end of our cultural commonality. Can you imagine a TV sitcom where a character makes a joke about QAnon ?
Anyway, let's rhapsodize nostalgic and sort through some thoughts & memories on TV in this thread...
