Coca-Cola has installed bottle-shaped patches of grass with trees, benches, and vending machines in 13 cities around the world as part of an advertising campaign. While the ads are well-done, some observers criticize Coke for commercializing public spaces and question if cities need the company to make parks. However, Coca-Cola is known for ambitious marketing initiatives, like a previous campaign between India and Pakistan that allowed people to gift sodas to strangers in the other country through a machine to promote happiness.
