At least TCM has a license now to show Tyrone's movies, and that's something that we fans have really pushed for.
I am hoping that they will do something special for him on his 100th birthday next year, including featuring Ty Power Jr. on one of their shows, like the Essentials or something.
I did have a running dialogue with the programming director, Charles Tabesh there, and he is a very nice man; however, I guess too many people wrote to him because his email appears to have been changed.
For now, the best thing we all can do is write to :

and choose "programming" or "request a movie" and start really pushing for Ty's centenary!
