One common 1937 advertisement said, "Its flavor knows no limits," and then proceeded to explain with six-year old Bobby and older family members all had a different reason to enjoy the cereal. By 1939, Ralston Purina had begun hoping to entice customers with box-top giveaways, such as a pen and pencil set that was still aimed at the whole family. By 1941, however, while their advertising still hoped to entice mothers and wives, the promotions had begun to be aimed at children, such as Tom Mix comic book give-aways. By 1951, Rice Chex and Wheat Chex were tied up with prized and box-top giveaways squarely aimed at children, such as ripcord helicopter toys. Ralston Purina attempted to redefine the Chex brand in 1956 by running copy on cereal boxes and in some newspapers which declared that they would no longer be putting prizes inside the boxes or targeting children: "This box contains 12 ounces of crunchable, munchable Wheat Chex - the only cereal made on purpose for Grownups." Even so, later ad campaigns for Chex varieties were not so restrained: "Now in every box of Sugar Frosted Chex, you can get one of nine different prizes. Kids will love the secret agent ring or invisible spy pen..." Tie-In Promotions The 1970s varieties Sugar Chex and Super Sugar Chex featured Casper the Friendly ghost on the box. Television and Radio Tom Mix During the 1930s, Ralston Purina sponsored the Tom Mix radio show, produced Tom Mix comic books and give-aways, and promoted Shredded Ralston (what became Wheat Chex) as, "the Tom Mix Bite Size cereal that's rich in 'Cowboy Energy.'"
