According to Wikipedia, when Joan Payson died, that left her husband in sole control of the team, a responsibility that he abdicated to his three daughters.
One of them, Sandra, eventually became a DirecTV satellite customer of mine until she died a few years ago. She had two "personal assistants" and she liked staging contests in which each one had to try to outjump the other.
It seems that this Miss Payson was having trouble with her cable TV. She had a cheap 19" TV connected to her Comcast box's RF output, but she would occasionally either accidentally change the TV off channel 3 or hit the A/V input button, and then she'd call the assistant who had arranged for the Comcast subscription at any hour of the night and she'd have to come down and straighten it out.
The other personal assistant contacted me to put in DirecTV without telling me why. Boy, was she disappointed when I completed the installation and she found that it connected to the TV the same way that the Comcast box did. She said she was going to be in big trouble for wasting money unless we could, A) make it so that the DirecTV couldn't inadvertently be disabled, and B) once we did that, conceal the fact that the same arrangement could have been worked out with Comcast.
I deleted all channels from the scan except channel 3, and then I put in a redundant, A/V connection, so if she hit channel up or down, it stayed on 3, and if she accidently hit "input" she'd get the same programming through the A/V input.
