What soft drink used the ad slogan "Obey your thirst" for almost two decades?

Sprite is a colorless, caffeine-free, lemon and lime - flavored soft drink created by The Coca-Cola Company. It was first developed in West Germany in 1959 as Fanta Klare Zitrone (“Clear Lemon Fanta”) and was introduced in the United States under the current brand name Sprite in 1961 as a competitor to 7 Up. Bottles of Sprite are usually a transparent green color with a green and yellow label whereas cans are colored silver, green, blue and aluminum bottles are colored a solid lime green.

in 1994, the brand's slogan was changed to "Obey Your Thirst" and jingles including it became urban-oriented, featuring a hip-hop theme song. One of the first lyrics for the new slogan were, "Never forget yourself 'cause first things first, grab a cold, cold can, and obey your thirst.” Under the new slogan, Sprite tapped into hip-hop culture by leveraging emerging and underground rap artists like LL Cool J, A Tribe Called Quest, KRS-One, Missy Elliott, Grand Puba, Common, Fat Joe, Nas, Chris Conn, Pete Ross and others in television commercials.

In 2006, a new Sprite logo, consisting of two yellow and green "halves" forming an "S" lemon/lime design, made its debut on Sprite bottles and cans. The slogan was changed from its long running "Obey Your Thirst" to just "Obey" in the United States and was outright replaced with "Freedom From Thirst" in many countries. This was the decade's first major shift in advertising themes.
