Coca-Cola is set to debut a new ad featuring a modernized version of the classic 1971 "I'd like to buy the world a Coke" song, first heard in a 1971 commercial. The ad, which focuses on America's 250th birthday, aims to create a positive association between the brand and its audience. The company is using its decades-old archives to find nostalgic material that can still appeal to a younger audience. Alex Ames, senior director of content and creative excellence at Coca-Cola Co., believes this could be a trend that will continue throughout the year. The new ad is part of a wider effort to revitalize the brand, following its controversial 1985 launch.
