In the months leading up to Apple’s highly anticipated smartwatch announcement everyone referred to the timepiece as the iWatch. Apple Watch is the official name, but it might not always have been that way. In an ABC News interview, Apple CEO Tim Cook slips up and refers to the Apple Watch as iWatch. Apple loves to use the letter "i" before its various consumer devices and services, but the Apple Watch bucks a trend alongside Apple Pay, the company’s mobile payments platform. Cook’s slip of the tongue occurs right at the end of the one-minute interview clip.
