Team Umizoomi premiered on Nickelodeon in 2010 and ran until 2015, mixing live action and animation to teach preschool maths through adventures in Umi City. The main team of Milli, Geo and Bot used their mighty math powers to help children who called for help. Clips from the opening and team calls later circulated online as nostalgic soundboard sounds, shared by viewers who grew up with the show and by editors looking for a wholesome, instantly recognisable team intro for memes and short videos.
