Trivia / 3-2-1 Contact

• Alternative Foreign Theme Song: When it was aired on European Spanish public television station RTVE, the music from the opening sequence was replaced with a completely new composition.
• Executive Meddling: When CTW originally devised the concept, they originally intended it to be hosted by American scientists, as they had based the concept on The Curiosity Show, an Australian science-based children's educational TV show that had been running since 1972. That program was hosted by Australian scientists Rob Morrison and Deane Hutton, who were consultants to CTW in the early planning stages for 3-2-1 Contact. PBS, however, insisted that in America, young hosts and presenters would hold the interest of the young target audience more effectively than middle-aged scientists would. Amusingly, only three years later, PBS ended up green lighting a children's science show which did not contain child hosts, Newton's Apple, which was initially hosted in its first four seasons by NPR science correspondent Ira Flatow, and hosted in the subsequent eleven seasons by David Heil, then assistant director of the Oregon Museum of Science and Industry.
• Keep Circulating the Tapes: Expensive if you're going for the VHS releases, and you can forget about DVD. This was in part because home taping was encouraged at the time the show was on the air.
• Technology Marches On: The Bloodhound Gang stories have the gang doing things like spending some time looking in reference books, calling organizations and using conveniently placed phone booths. Modern stories would have them all using smartphones to quickly look up info and communicate with each other, not just Ricardo taking incriminating pictures. For instance, "The Case of the Dead Man's Pigeon" would have been thwarted with one look through Wikipedia at the will reading instead of one of them running to call the Audubon Society.
