I have many TV programs that do not have ads.
In the 1970s, TV programs had typically 48 minutes of content.
Now, TV programs have between 38 and 42 minutes of content.
Half-hour TV programs have comparable reductions in content.
Broadcasters cut out parts of the older programs to fit them into the new lengths. In so doing, they cut out some content that is essential to the program.
I happened to notice on the Directv guide this morning, Brady Bunch has a marathon on TVLand and each episode runs 45 minutes.
In the 1970s, TV programs had typically 48 minutes of content.
Now, TV programs have between 38 and 42 minutes of content.
Half-hour TV programs have comparable reductions in content.
You appear to suffer from the common misconception that most people have. You have it exactly reversed. The commercials are the content. The shows themselves are nothing but a vehicle to bring the ads to you.
