Top Downloads of 2014

You, Download.com nation, got more than 630 million apps from our site in 2014. To put the number in perspective, that's more than dollars spent seeing "Guardians of the Galaxy" ($332 million gross), Netflix subscribers (53 million), World Series game 7 watchers (23.5 million), Apparently Kid viewers (18 million), and US buyers of Taylor Swift's "1989" (3.3 million).
