Coke wants to make Londoners even happier this summer. People traveling around the city will likely come across some of the 300
“Happiness Meters” billboards the brand has purchased in the latest layer of its “Open Happiness” campaign.
The level of happiness will be based on positive, or negative “mood” words being tweeted around the area, as well as mentions of the brands #ChooseHappiness hashtag. The more positive the tweets, the higher the meter will rise.
Other marketing elements will support the billboard campaign, including sampling and giveaways of branded merchandise.
