Critical Role is an American web series in which a group of professional voice actors play Dungeons & Dragons. The show started streaming in March 2015, partway through the cast's first campaign. "Campaign one" ran for 115 episodes, and ended in October 2017. The cast started playing "Campaign two" in January 2018, which is still ongoing as of January 2020. A number of one-shots were aired in the hiatus between the two campaigns.
The series is broadcast live on Thursdays at 19:00 PT on the Critical Role Twitch channel, with the video on demand (VOD) being available to Twitch subscribers immediately after the broadcast. On the Monday following the live stream, the VODs are made available for the public on Critical Role's website and uploaded to their YouTube channel.
