It aired from September 1, 2008 to March 25, 2013, with a total of 66 half-hour episodes produced over two seasons, and lasted for four years. The computer generated show is produced by The Jim Henson Company and PBS member KCET in Los Angeles, California using the Henson Digital Puppetry Studio. The show is produced by motion capture which allows puppeteers to voice digitally animated characters in real time.

Production began in January 2003 with 42 half-hour episodes of Sid the Science Kid having been ordered. The series debuted on PBS Kids along with Martha Speaks on January 5, 2008, with a two-year on-air commitment. The original working title for the series was "What's the Actual Big Idea?" and the central character, Sid, was originally named Mario. The series is the second CGI animated show to use the motion capture technique after Donkey Kong Country.
