Big Blue Marble was a half-hour children's television series that ran from 1974 to 1983 on numerous syndicated and PBS TV stations. Distinctive content included stories about children around the world and a pen-pal club that encouraged intercultural communication. The name of the show referred to the appearance of Earth as a giant marble, popularized by a famous photograph of the same name taken in December 1972 by the crew of Apollo 17. Each episode featured a segment about the real life of a boy and a girl, one American, the other foreign. The show also had occasional stories about world ecology. In addition there was a weekly segment in which a singing globe "Bluey" invited viewers to write letters to the show, often requests for pen pals. The address to send the letters was in Santa Barbara, California. The character was voiced by executive producer Robert Weimer. Production personnel included creators Ken Snyder, Henry Fownes, and Robert Garrison, and later executive producer Robert Weimer, producer Rick Berman, writers Lynn Rogoff and directors Joe Napolitano, Joseph Consentino, Tom Hurwitz, John McDonald, J.J. Linsalata, Pat Saunders, and Ira Wohl. Robert Saidenberg was supervising producer, Peter Hammer supervising film editor and Dale Glickman post-production supervisor of the series late in its run. Paul Baillergeon composed much of the series' music. Weimer often rewarded staff members with the opportunity to pitch story ideas and direct segments of the series. As a result, many got their first chance to work in that capacity. Some children featured on the show who went on to high-profile careers are: Tisha Campbell, Fran Jolie and Kevin Clash. Before they were well-known, actors Sarah Jessica Parker and Kelly Reno were featured in dramatic segments serialized in the series.
