Trolling the competition with a 1-cent Whopper.
This has to be one of the boldest competitive campaigns I’ve seen. Burger King became McDonald’s #1 troll by offering 1-cent Whoppers through its app — but only if you were near a McDonald's. No surprise, it went viral, rocketing their app to the top spot in 48 hours. They essentially hijacked every McD's restaurant, turning them into a Burger King promotional machine.
