Rovio's Angry Birds was downloaded 6.5 million times on Christmas Day, AllThingsD reports.
The figure includes both free and paid downloads for Angry Birds, Angry Birds: Rio and Angry Birds: Seasons, and is a huge increase over the previous year's total of 2 million.
"We're really excited to have such a massive number of new people get acquainted with Angry Birds over the holidays," said Angry Birds creator Ville Heijari. "We have exciting new releases lined up for 2012, and can't wait to introduce them to the public."
Data from the mobile analytics firm Flurry indicates that a total of 6.8 million iOS and Android mobile devices were activated on Christmas Day - just 300,000 more than the number of Angry Birds downloads - smashing last year's record-breaking 2.8 million activations.
Records continued to fall on the week leading up to New Year's Eve (December 25 to December 31). In total, 20 million iOS and Android devices were activated, and 1.2 billion applications were downloaded.
