Coca-Cola has used a variety of slogans and commercials over the years, but their "Hilltop" commercial in 1971 introduced the world to a song.

The song was "I'd Like to Teach the World to Sing (In Perfect Harmony)." It was a song of hope, peace and unity and the ad featured a happy multi-ethnic cast who apparently were setting their differences aside so that they could enjoy a Coke together.

Who knew a carbonated beverage could lead to world peace? Apparently all people need to do is "buy the world a Coke and keep it company." The jingle was so popular that it was recorded into a studio song and performed by The Seekers and The Hillside Singers.

When people are grown up, they can make decisions on these jingles and buy products. However, who wants to grow up?

No. 1: Toys R Us Kids

Not only was Toys R Us touting the wonder of their products, but they were also telling kids that it was just fine if they stayed young forever so that they could keep enjoying being a "Toys R Us kid."

In other words, the company was shooting for brand loyalty pretty early on. The company was not exactly conveying that children should run off to Neverland with Peter Pan, but the jingle certainly suggested that staying young forever was a good way to live life.

Toys R Us also combined the song with imagery of their giant store so that kids could imagine walking through the toy aisles and having access to the "biggest toy store there is" featuring "a million toys that I can play with."

The jingle was apparently memorable enough as Toys R Us remains one of the most popular toy stores today.
