Group influences play an important role in the success of Yum Brands, which owns KFC, Pizza Hut, and Taco Bell. Yum Brands' advertising campaigns target different social groups. KFC targeted health-conscious individuals with its campaign featuring celebrity chefs endorsing grilled chicken. Taco Bell engaged consumption subcultures on Instagram with its "Live Mas to Win Mas" campaign. Pizza Hut customized its offerings to different tastes and promoted social interactions through online communities and mobile apps. These campaigns were generally effective in driving sales promotions and creating viral buzz, though KFC's grilled chicken also led to some negative reactions from franchise owners focused on that product.
