Rovio is used to celebrating milestones, and now the studio has another one to tick off - the company's animation series Angry Birds Toons has amassed over 400 million views since its launch in March 2013.

With the videos deployed across its mobile line up, the Finnish firm estimates that this success equates to "well over 100 million views per month" across the various games in the Angry Birds franchise.

Short and sweet

Rovio also notes that the animated Angry Birds shorts have been "a big hit" with its network of TV partners around the world, although no exact numbers for views or ratings have been given.

To celebrate the milestone, Rovio has moved to put the first Angry Birds Toons episode - Chuck Time - on video-sharing website YouTube.

The success of Angry Birds Toons comes at a pivotal time for Rovio, with some commentators speculating about the longevity of the Angry Birds franchise and the role Rovio will play in the mobile scene in the year's ahead.

Indeed, this month has seen the firm publish its first third-party release in the form of Nitrome's Icebreaker: A Viking Voyage thanks to its new Rovio Stars initiative, with Rovio looking to associate its brand with IP outside of the Angry Birds family.
