Over 7 million people were on Steam yesterday
7 million people were all logged into Steam at once on Sunday, December 1, 2013.
The exact figure? 7,190,547.
This is a new peak number of concurrent users for Steam, which has 65 million members total.
The likely reason is Steam's wallet-busting Autumn Sale.
The statistics page also reveals that Dota 2 is currently the most popular game on Steam. Today's peak lists 531,279 players all at once.
Steam's Autumn Sale ends tomorrow. May our bank accounts rest in peace.
