Google I/O (simply I/O) is an annual developer conference held by Google in San Francisco, California. I/O showcases technical in-depth sessions focused on building web, mobile, and enterprise applications with Google and open sources such as Android, Chrome and Chrome OS, APIs, Google Web Toolkit, App Engine, and more.

I/O was inaugurated in 2008, and is organized by the executive team. "I/O" stands for input/output, as well as the slogan "Innovation in the Open".[2] The event's format is similar to Google Developer Day.
