Several television programs originating in the Twin Cities have been aired nationally on terrestrial and cable TV networks. KTCA created the science program "Newton's Apple" and distributes a children's program today. A few unusual comedic shows also originated in the area. In the 1980s, KTMA (now WUCW) created a number of low-budget shows, including the cult classic "Mystery Science Theater 3000" (which later aired on The Comedy Channel/Comedy Central from 1989 to 1996 and the Sci-Fi Channel from 1997 to 2004). The short-lived "Let's Bowl" (which aired on Comedy Central) started on KARE, and the PBS series "Mental Engineering" originated on the St. Paul public-access television network.
