Encyclopædia Britannica and a panel of history teachers. Educational goals Rayvid noted that history can be more politically charged than the more cut-and-dried geography, noting, for instance, how the nature of historical documents led to bias toward male white stories. Moving away from a pro-American bias, in a World War II themed episode, the show spoke candidly about American internment camps for Japanese-Americans, citing this as an example of how "We try to deal with controversy in a very straightforward, educational way". Another aim of the show was to give young viewers "a sense of time", in that things happened before they were born that influenced their current reality. Production The music on the show was performed by The Engine Crew. The music package included the theme song and the songs about clues in the engine room. The theme was played in the opening and closing sequences. When the contestant was heading for the trail of time, the theme was sometimes edited after the crew sang, "We're on the case" and the villains say, "And they're chasing us through history!" (used in first season). In the second season, when the contestant headed for The Trail of Time, the ending was normal instead of the villains singing the end part. The show's main theme song was written by Sean Altman of Rockapella and David Yazbek, and is sung by The Engine Crew. Like its predecessor series, which faced outdated information during its run, the end of every episode had an audible disclaimer from Lynne Thigpen stating that "All historic information has been verified by Encyclopedia Britannica (and was accurate as of the date this program was recorded)." with the recording date shown with the copyright information at the end of each episode. The show was funded primarily by the Corporation for Public Broadcasting and by the annual financial support from the viewers/stations of PBS throughout the entire series. Delta Air Lines and the National Endowment for Children's Educational Television both provided funding during the show's first season. Scott Wells served as the 3-D animator while Raeford Dwyer was the animation producer; together they gave the show a style that mixed computer-treated video FMV performances computer-generated two- and three-dimensional animation and special effects. A live version of the World and Time shows ("Carmen Sandiego Live") was performed at 85 sites across the United States and Canada from 1993 to 1997. Critical reception
