Coca-Cola Zero re-imagines 1971 ad.

Everything old is new again. A new TV spot for Coca-Cola's new zero calorie soft drink, Coca-Cola Zero, re-imagines the cola company's now classic 1971 ad, "Hilltop," as "Chilltop."

The original ad, filmed on a hilltop in Italy, featured an international group of young adults singing the song, "I'd Like to Buy the World a Coke." Coca-Cola Zero's new ad -- lensed on a rooftop in Philadelphia -- features artist G. Love surrounded by a handful of people, singing the re-envisioned version: "I'd Like to Teach the World to Chill."

"Chilltop" was created by ad agency Crispin Porter + Bogusky of Miami. The campaign also includes radio, cinema, outdoor and digital programming.

The TV spots debut June 27 during NBC's "Las Vegas," CBS' "Two and Half Men" and Fox's "Hell's Kitchen." Baseball enthusiasts, though, were offered a sneak peak of the commercial on a high definition monitor during a June 26 Atlanta Braves game at the Turner Field in Atlanta.

In 1971, two acts experienced success with the same song adapted from the Coca-Cola jingle. "I'd Like to Teach the World to Sing (In Perfect Harmony)" by the New Seekers and the Hillside Singers peaked at No. 7 and No. 13 on Billboard's Hot 100, respectively.
