Surprisingly, or maybe not at this point, YouTube has been a significant part of the conversation during CBS' TCA day, first because of the announcement prior to the opening session with CBS Entertainment Chairman Nina Tassler that the network's new late night star James Corden is going to tape the August 21 edition of "Late Late Show with James Corden" at YouTube Space L.A. in Santa Monica with a guest list comprised of popular YouTubers.
Then, along came "Supergirl."
For some reason, there are no plans at the moment for any cross-overs or narrative references between "Supergirl" on CBS and "The Flash" and "Arrow" on The CW, even though the title characters (and many of the supporting players in each) reside in the D.C Comics universe, all three shows are produced by Berlanti Productions and Warner Bros. Television, and CBS and The CW are sibling networks. Tassler did say Monday morning that there will be "crossover promotions." Melissa Benoist plays the iconic title character.
Fun fact: When "Supergirl" debuts on October 26, it will be the first time since 1949 that CBS will not have sitcoms scheduled from 8-9 p.m. on Monday nights.
