Over one million Call of Duty players forked out for premium Call of Duty Elite memberships in the service's first six days of availability.
In comparison, the premium subscription services for Netflix, Hulu Plus, Sirius XM and Xbox Live each reached one million paid subscribers after approximately one year, according to CoD publisher Activision.
Elite memberships are included with the Hardened edition of Modern Warfare 3 or can be bought separately for £34.99/$49.99 through Xbox Live and PSN.
Since Elite's launch on November 8, over four million gamers have registered for the online service, which also includes a free tier.
More than 80,000 Elite clans have been created, 100,000 user-generated videos have been uploaded to Elite, and the service has had more than three million daily logins.
"The audience response to Call of Duty Elite's premium service has been beyond our expectations, and we want to thank Call of Duty players around the world for their unprecedented enthusiasm," said Activision Blizzard CEO Bobby Kotick.
"The number of gamers who have registered for Call of Duty Elite further illustrates how this service is poised to redefine social gaming and set a new bar for interactive entertainment."
Call Elite's launch hasn't been without its troubles though, something Activision Publishing CEO Eric Hirshberg acknowledged today.
"The demand for Call of Duty Elite at launch was so overwhelming, that for the first several days, the service did not perform up to our or our fans standards. I want to personally thank our fans for their patience.
"Our teams have been working around the clock to get the service scaled up to meet demand. I'm very pleased to announce today that the service is now performing stably and anyone who wants to try Call of Duty Elite is now able to do so."
Due to the early troubles, Elite premium Founder members are to receive an additional 30 days of the service free of charge.
