Photos: 15 years of Gmail

​Gmail launches in 2004, and it's not an April Fool's joke

With its launch on April 1, 2004, many people thought Gmail was an elaborate April Fool's prank. It was anything but that, and the past 15 years have proven how serious Google is about email.

At launch, Gmail offered 1 GB of storage, which was unheard of at the time. It also had sophisticated search features and introduced threaded email conversations, a feature that is now nearly universal in email clients.

Early Gmail users had to get an invite from an existing user. I was lucky enough to get mine early in the public beta, and I am still using the same address!

The past 15 years have been innovative ones for Gmail, and Google shows no signs of stopping.
