Coca-Cola made its packaging smarter in 2015 with the launch of its Come Alive marketing campaign in September. Consumers in the South Pacific benefited from colour-changing labels brought to live by cans and bottles chilled to their optimal drinking temperature throughout the summer. Not only that, but image recognition technology connected consumers to giveaways and gift experiences with a quick snap of the stat-of-the-art can. The packaging is aimed to tempt in more teens, said the brand but intelligent packaging isn't only for kids. In March 2015, Diageo unveiled its "smart bottle" of Johnnie Walker whisky in Barcelona, which uses electronic sensors to detect if a bottle has been opened and where it is along the supply chain.
