The previous record for concurrent users was 9.5 million
Steam is on a record-breaking spree. This year there have been three instances of the client shattering its previous concurrent usage record and setting a new one. It first did it in January, when the number of concurrent users breached the 8.5 million mark; in March, when it recorded over 9 million simultaneous users; and on Sunday, when the client witnessed over 10 million logins.
Based on Steam’s game stats page, the number of concurrent logins first exceeded the 10 million mark a few minutes before the clock struck 11 (PST) and stayed at those record levels until a few minutes after noon. You don’t have to be a genius to figure out that many of these record logins were on account of the ongoing Steam Monster Summer Sale. Set to run until 10:00 AM PST, June 22nd, the event presents Steam users with new deals and discounts on a daily basis.
