During "Crisis On Infinite Earths", I can't help but notice that the some of the other earths belong to a few popular DC live action shows. (I.e. Titans, Smallville, and Black Lighting.) As well as shows that've finished airing over 10 years ago (I.e. Batman 1966 series, and Birds of Prey.) What do you guys think? Are the shows part of the Arrowverse or not?
