Jennifer Maas TV Business WriterParamount Plus and Showtime are two separate subscription services owned by the same company in a market that is already overcrowded with streaming and pay-TV competition. But that’s the way it’s going to stay for the two ViacomCBS brands — for now at least — as Paramount Plus president of original scripted series Nicole Clemens says the young streamer continues to carve out its identity as the home of “big blockbuster originals” versus Showtime’s slightly “more coastal” audience.“I think they’re complementary and I think there’s going to be some overlap in a Venn diagram,” Clemens told Variety Tuesday, following Paramount Plus’ day of presentations at the virtual Television Critics Association winter press tour.
