User blog comment:CaseCracking100/Did the Arrowverse get bigger, or is it just me?/@comment-43311145-20191219231404

Yes and no. Things like Titans, Black Lighting, Lucifer definitely. But there is a little inconsistency with Smallville (Everything on this is on talk page) and Burtonverse (It was at the screen for the 10 seconds and they ducked it up). Also i wouldn't say that in that sentence because it shows like arrowverse is a main earth and it is definetly not, but you can give a credit to Crisis On Infinite Earths that it made shared multiverse amongst live action DC Comics Universes.
