^^^^^^^But the original post said nothing about music, but whether she got "discovered" and put on TV because she was a Jackson. None of the brothers were known as actors, and being a musician has no pull as far as Hollywood goes. The brothers popularity had kinda faded around that period (and they were considered a teen idol act. Teen acts aren't taken seriously by the powers that be), so just being a Jackson wouldn't have helped her anyway as far as getting on Good Times. It was Joe's idea that she make a record later, not Janet's.
What is the point exactly? All I'm saying is that whether it was acting or singing, the Jackson last name did open doors for her and it probably helped to get her auditions. Janet is a pretty good actress though and i'm sure she wouldn't have scored those TV roles if directors hadn't been genuinely impressed with her.
