Gow will lead a team of three "digital content innovators" working across Trinity Mirror's regional brands, in addition to a new role as deputy digital publishing director for Trinity regionals, under David Higgerson.
"Our digital platforms are already experiencing unprecedented growth, and winning awards and plaudits regularly," Higgerson, Trinity's director of digital publishing, said in a press release.
"In Alison, we have the best possible person to ensure we innovate with content to find many more ways of keeping audiences engaged with our content online."
The new team will operate from the company's regional newsrooms, including the Manchester Evening News, Liverpool Echo, the Newcastle Chronicle and the Western Mail, in creating original content for online and mobile. Gow will begin recruiting additions to the team in the new year.
"One of the joys of the digital revolution is that it gives journalists so many opportunities to reach new audiences, and tell stories in myriad ways," she said in a statement.
"I'm excited to work with other editors to make our newsrooms places where innovation and editorial excellence run hand in hand."
The digital innovations team is the latest in a series of new digital ventures within Trinity Mirror in 2013. After cutting a number of editorial roles in January, Trinity announced the introduction of a 'newsroom 3.0 model' in February, a group-wide data journalism unit in March, an internal newswire in June and experiments in socially shareable journalism with UsVsTh3m and Ampp3d.
