Canadian firm Airborne Mobile is ending its mobile game publishing activities, following a management buyout extricating it from former parent company Cybird.

The company revealed the news in an email to business partners, in which it described "a series of job changes that while painful in the short-term, will serve to expand the Company's focus on profitable product lines while maintaining its renowned creativity."

Co-founder and president Andy Nulman has confirmed to MocoNews that those painful changes include laying off 27 out of 100 employees, and said the shift away from games is because they are costly to develop and hard to distribute.

Airborne's mobile game activities have included branded games for Maxim magazine and the Family Guy cartoon, as well as action titles Alien Hominid and Boulder Dash ME.

The company will now focus on ringtones, wallpapers and other content, as well as helping brands launch off-portal strategies.
