According to the show’s IMDB page, there are 237 episodes of Cosmic Disclosure organized into 17 seasons over the years 2015 through 2020. The cast and crew page lists David Wilcock as the host for 164 episodes from 2015 until 2018 (which seems to cover the entirety of seasons 1–11) and Corey Goode as an interviewee for 139 episodes from 2015 until 2018 (again, seasons 1–11). After that, it looks like the show was hosted by George Noory (with Jay Weidner acting as a host from 2017 until 2019, overlapping with Wilcock and Noory).
