Steam has broken the 8 million concurrent users milestone for the first time in its history - thanks mostly to its popular summer sale. On Sunday evening over 8 million gamers were using the service at the same time as the Steam Summer Sale began to wind down.
The last milestone for concurrent users on Steam - according to its stats page was around 7.5 million, which occurred over Christmas 2013. The new record high of 8,020,834 was recorded at 16:03 PDT on Sunday June 29.
The Steam Summer Sale ends at 10am PDT today.
