I last looked at the race to a billion in September 2010. I’ve now added a few more data points to the tracked platforms and also added points for the major console game platforms and Symbian.
The chart shows the cumulative number of users (approximated by units sold) for 11 platforms indexed to the same starting date. The horizontal axis is the number of quarters since a platform launched. Every fourth quarter is numbered so each number on the axis represents a new year. The last number on the axis represents 10 years.
The vertical axis is the cumulative number of users on a logarithmic scale. Each number of the vertical axis is 10x more users than the previous number. The top of the graph represents a billion users.
The overall chart shows how quickly a platform has grown and is bounded by a billion users and a decade of usage.
