Commercial TV programming?

rtjhnstn thought this was worth mentioning said

Last night my family watched “Legally Blonde” on PBS. It was the 1st movie we watched as a family in 6+ weeks. My daughter & wife chuckled at appropriate parts of the movie. It was very enjoyable family entertainment.

In this time of social distanting, why aren’t major networks promoting and showing similar content? This question applies to OTA and cable broadcasters.

Please assume answers other than just money from advertisers.
