Coca-Cola puts names on bottles as part of their "Share a Coke" marketing campaign, which started in 2011. The idea is to personalize the bottles by replacing the usual Coke logo with popular first names or nicknames. This personalization catches consumers' attention because people are naturally drawn to seeing their own names, a psychological effect known as the "Cocktail Party Effect." This tactic encourages people to find bottles with their names or the names of friends and share them, creating a personal and emotional connection with the brand. The campaign has been highly successful globally, increasing sales, boosting consumer engagement on social media, and revitalizing the brand, especially among younger generations. It also allows people to customize bottles online in some markets, enhancing the personal experience further. In summary, Coke puts names on bottles to create personal connections, increase attention and engagement, drive sales, and make the brand feel more relevant and relatable to consumers, especially younger ones.
