At the I/O 2015 developer conference today, Sundar Pichai, Google’s senior vice president of product, announced that Chrome has passed 1 billion active users.

Less than a year ago, Google revealed Android has over 1 billion active users. These are indeed Google’s biggest ecosystems.

Google also shared that Google Search, YouTube, and Google Maps all have over 1 billion users as well. Gmail will reach the milestone next; it has 900 million users.

Chrome is arguably more than a browser: It’s a major platform that Web developers have to consider. In fact, with regular additions and changes, developers have to keep up to ensure they are taking advantage of everything available.
