ELI5: Did T.V stations back then used to play the national anthem then cut to static? If so, why?

In the past, TV networks didn’t have enough cone to to broadcast 24 hours. So at a certain point it would just cut off broadcasting. Different stations had different ways to signal the end of the broadcast. I’m not sure if any ending with national anthem, most started that way though. Following the ending of their end of transition message, the broadcast would end, causing the TV to cut to static.
