The Holiday season proved to be a major success for both Disney Mobile and Storm8, as both developers revealed they saw a huge surge in mobile downloads and installations.

Disney Mobile revealed that downloads during the holiday period (Dec. 22 through Dec. 28) of 2012 were up 98 percent from 2011. During the five-day period, Disney mobile reports it had more than 15 million downloads. The developer also reported its peak level of daily active users saw a year-over-year increase of almost 400 percent, reaching more than 7.5 million daily active users (DAU). As we noted back in December, Disney Mobile was providing some major updates to its flagship games and also rolled out new titles like Monster, Inc. Run, Where’s My Holiday? and Nemo’s Reef.

Meanwhile, as Inside Mobile Apps notes, Storm8 saw huge growth on Christmas Day. The company tells us that it saw downloads increase fourfold on that day compared to the numbers it usually sees on Tuesdays. Storm8 also says it had 2.5 million hours of gameplay and its average revenue per daily active user was approximately 4.5 times above the normal level. The week before Christmas, Storm8 launched its newest social casino title, Bingo!, under its Shark Party brand.

Success stories like these aren’t uncommon during the holidays, albeit not always as dramatic. Mobile app monetization firm Flurry reports that the week between Christmas and New Year’s Day was the biggest week in terms of new device activations and app downloads across iOS and Android.
