The show was targeted to children, but attracted a sizable adult audience. Many episodes featured commercial tie-in merchandise, like toys and mail-order premiums, that were advertised during commercial breaks. Many of the ads for corporate sponsor Ralston Purina's Chex cereals used the show's space opera motif in their pitches. A unique feature of the TV and radio adventures was that the premium of the month was often worked into the story action. This permitted young viewers to feel that they were participating in the radio or televised adventures. "Space Patrol"s best known premium was a "Name the Planet" contest wherein the winner was awarded the program's Terra IV spaceship. The prize was a giant trailer in the shape of the series' space craft. One of the many "Name the Planet" commercials may be viewed online.
