The Professor Rossa Show is a Canadian-American children's comedy-educational sitcom produced by Sanford Productions and Apple Entertainment for The Greeny Channel XD. It started in 2008 and runs to this day. The show uses footage from the 1981-2001 Chilean children's television show El Mundo del Profesor Rossa (The World of Professor Rossa), along with new footage shot by Sanford Productions at The Bridge Studios, to create an original, unrelated plot for each half-hour episode.
