Mini-Timeline:

1957 - 7up starts advertising on TV and radio.

In 1963, 7up began selling a diet lemon-lime drink called Like. Renamed in 1969 to 7up.

In the 1970s 7up started making 1 liter bottles with the label, "Follow the Liter." (Clever)

In 1986, Dr. Pepper and Seven Up merged into one company.

In 1987 Cherry 7up and Diet Cherry 7up were released, and Spot was created.

In 1999, 7up launched the Make 7 Up Yours marketing campaign, with Orlando Jones playing
the part of the guy who makes 7up.

(And recently, they changed the logo on the can)
