What is snl countdown?

As an AI language model, I do not have access to the current or upcoming SNL Countdown episodes as they have yet to be announced. However, SNL Countdown was a digital series produced by Saturday Night Live, which aired in anticipation of upcoming SNL episodes. The series was hosted by SNL cast members and featured behind-the-scenes footage, interviews with guests and performers, and previews of upcoming sketches and skits. The series aimed to generate excitement and anticipation for new episodes of Saturday Night Live.
