Using Computer Vision to Help Win $1 Million in Mountain Dew's Big Game Contest Last night during Super Bowl LV, Mountain Dew ran an ad featuring John Cena riding through a Mountain Dew-themed amusement park. Bottles are scattered all over the scene: neon signs on buildings, in fun house mirrors, and flying out of the car trunk. At the end of the ad, John Cena challenges the audience: The first person to tweet at Mountain Dew the exact number of bottles that appear in the commercial is eligible to win $1 million.
