Chain: 7-Eleven
Introduced: 1980 

What a relief that the Big Gulp escaped Mayor Bloombeg's banhammer on large, sugary drinks. Big Gulp is the poster boy for comically-large soft drinks, and it's popularity is to the point where 7-Eleven markets itself as the "Home of the Big Gulp." It's the drink size that swallowed an entire convenience store. But perhaps its biggest claim to fame is one of the funnier instances of product placement in cinema history.
