Ubisoft claims a couple of one-day company sales records were set by Tom Clancy's The Division, saying no previous release has sold through more units in its first 24 hours, nor have they ever sold more digital copies of a game across all platforms in a single day. Here's part of their announcement, which does not specify how many copies were sold:

Today, Ubisoft announced that Tom Clancy’s The Division has sold through more copies in its first 24 hours of availability than any previous title in the company’s history*.

“We’re extremely happy with The Division’s record-breaking launch,” said David Polfeldt, Managing Director, Ubisoft’s Massive studio. “The Division really represents Ubisoft at its best, with the Massive team and all the teams at our associate studios working at maximum capacity in highly-productive collaboration to deliver an incredibly innovative and entertaining new game.”

The Division also set Ubisoft records for total digital full game sales in a single day across all platforms, including Windows PC, Xbox One and PlayStation 4. And with the addition of The Division, Ubisoft now has three of the top four** most successful new game brand launches in the history of the industry.

“The launch of The Division is a tremendous achievement for Ubisoft, and demonstrates our unrivalled capacity to create fantastic new game brands and transform them into entertainment blockbusters,” said Yves Guillemot, Co-Founder and CEO, Ubisoft. “This is a momentous day for Ubisoft, but more importantly it marks the start of millions of players’ enduring engagement in The Division’s game world, which we are confident they will love.”
