I cant ignore the NBA any more than I do.
I gave up on the NBA probably in the 1980s.
Back in the VCR era... I set it to record a movie on TBS.
Watching the tape the next night, it goes to split-screen - half-movie, half NBA game, with the caption, “You can watch this game on TNT”.
Don’t remember how long split screen lasted, maybe a minute?
TBS might have done it a couple of times during the movie.
Guess the ads/audience revenue must have been higher enough for them to try to annoy and perhaps lose audience on TBS in the attempt to poach from themselves.
