Prizes have been inserted into every package of Cracker Jack continuously since 1912. W.K. Kellogg was the first to introduce prizes in boxes of cereal.

Frito-Lay is a world icon in the field of in-package prizes. Besides being the current owner of Cracker Jack, the U.S. popcorn confection brand known for the "Prize Inside", Frito-Lay also regularly includes tazos and tattoos in packages of Lay's chips worldwide. In parts of Latin America, Frito-Lay has even introduced a brand called "Cheetos Sorpresa" (English: Surprise), which includes a licensed prize (from movies, television, and video games) in every 29–gram bag. Aaron Montgomery Ward's mail order catalog created a network that included mailing, mail order, telemarketing, and social media. Today, the mail order catalogue industry Montgomery founded is worth approximately 100 billions of dollars, and generates over 2 trillion only in [incremental] sales and supports till this day an estimated 10.9 million jobs either directly related to marketing industry or dependent upon it. Mail order pioneer Aaron Montgomery Ward knew that by using the technique of selling product directly to the consumer at appealing prices could, if executed effectively and efficiently, revolutionize the market industry and therefore be used as an innovative model for marketing products and creating customer loyalty. The term "direct marketing" was coined long after Montgomery Ward's time. In 1967 Lester Wunderman identified, named, and defined "direct marketing". Wunderman — considered to be the father of contemporary direct marketing — is behind the creation of the toll-free 1-800 number and numerous mail order based loyalty marketing programs including the Columbia Record Club, the magazine subscription card, and the American Express Customer Rewards program. On May 1, 1981 American Airlines launched the AAdvantage frequent flyer program, which accumulated “reward miles” that a customer could later redeem for free travel. Within a few years, many other travel industry companies launched similar programs.
