This summer marks the 15th anniversary of the iPhone’s debut. The smartphone changed how we live, but its innovations also heavily influenced tech policy in Washington for the next decade and a half.

A good example is the push to regulate app stores. The first iPhone came with a handful of pre-installed apps, but the option of downloading third-party apps would not happen until the 2008 launch of Apple’s App Store. Today, various attempts to regulate app stores are among the most discussed bills in the tech policy world.
