Oh my! Each of those could almost be a thread unto itself.
We had three channels, all out of Detroit. Local stories were the sole province of the local radio stations and newspapers.
With only 15 minutes, the news programs focused on broadcasting actual news. No big emphasis on telling the viewer what they should THINK about it as is the case today.
My first recollections of the Tonight Show featured Jack Parr as the host. I'm sure some here recall when it was hosted by Steve Allen! That program died for me when Carson left.
On another thread, someone here mentioned having once met William Boyd. His character, Hopalong Cassidy, was my earliest TV cowboy hero. I even had a Hopalong Cassidy bedspread.
Rabbit ears didn't work where I lived. Most houses had an antenna on the roof. The well to do had them on towers.
Waiting for the television to "warm up"? Yup. Haha, I still have to do that with my Panasonic 50" flat screen. So much for progress.
I don't think I ever saw a TV repairman. My dad was good with electronics and was able to troubleshoot and fix any TV problems.
An uncle had one of the first TV remotes. IIRC, it had three buttons that made a "ding" sound when pushed. It used sound to change channels and turn the set on and off.
Yes, it seemed like every adult smoked ... actors, politicians, teachers, doctors, and most kids' parents. Television carried a LOT of advertising for tobacco and alcohol products in those days.
Although I wasn't a big Flintstones fan, those three channels did broadcast a great number of really good programs. Somehow I don't think today's "reality TV" dreck would have fared well back then.
