Steam is your premier digital distribution platform, world, and Valve is excited to report that you’re the reason it keeps growing. For the seventh year in a row, Steam sales are up by over 100 percent. This probably has something to do with the 40 million account holders, and a year in which the service crossed the five-million-concurrent-user threshold. For a sense of scale, users worldwide downloaded over 780 petabytes of data over the course of 2011. A single petabyte is 1000 terabytes, while a terabyte is 1000 gigabytes. Your PlayStation 3 or Xbox 360 probably has somewhere between 120 and 320 gigabytes of space on its hard drive. That is a staggering amount of data.
