Which soda brand is known by the slogan 'the real thing'?

The soda brand known by the slogan “the real thing” is Coca-Cola.

Coca-Cola used “It’s the Real Thing” as a major advertising slogan beginning in 1969. The wording presented Coca-Cola as the genuine, original choice rather than merely another soft drink, and it became one of the brand’s best-known campaigns.

The slogan was closely associated with the 1971 “I’d Like to Buy the World a Coke” advertisement and song. That campaign connected the drink with peace, togetherness, and international friendship, helping turn a product advertisement into a memorable piece of popular culture.

Coca-Cola has used many other slogans, including “The Pause That Refreshes,” “Things Go Better with Coke,” “Always Coca-Cola,” and “Open Happiness.” “The Real Thing” is therefore a historic campaign line, not Coca-Cola’s only slogan or necessarily its current worldwide tagline.
