Cook was roundly (and light-heartedly) mocked on Twitter after the game, over the quality of a picture he took from the pitch.
The picture, taken with an iPhone (it'd be a bit of a scandal if he used a Galaxy), is fairly out-of-focus and poorly-composed, which is fairly understandable given the circumstances.
However, it's not the best advert for the iPhone camera, which Apple is currently singing the praises of in its 'Shot on iPhone 6' advertising campaign.
Naturally, given the chance to have a pop at Apple and other people's photography skills in one go, Twitter had a field day.
Later, Cook posted another picture from the stadium which was a little better, but it was too late. The damage was done.
Super Bowl 50 ended with a win for the Denver Broncos, who beat the Carolina Panthers 24-10.
