Which of the following celebrities is an important part of the Twitch cultural experience,with a dedicated channel on Twitch that streams old episodes of their TVshow24/7?

Bob Ross is a significant figure in Twitch culture, with a dedicated channel that continuously streams episodes of his show, The Joy of Painting. This channel is popular for its calming, positive atmosphere, often used for background viewing or as a "comfort stream." Johnny Carson, Oprah Winfrey, and Jerry Seinfeld, while iconic celebrities, do not have dedicated 24/7 channels streaming their classic content on Twitch in the same way Bob Ross does, making them less central to the platform's unique cultural experience.
