Courtney Holt has been named chief operating officer of Maker Studios, the digital production company he began advising after leaving his position as president of MySpace Music in February 2011.

Company co-founder Dan Zappin told AllThingsD that Holt’s expertise will help Maker Studios evolve and grow, possibly into the mobile sphere initially, although the company has broader aspirations.

Maker Studios specializes in creating, distributing and promoting professional quality online content. Currently its operations are ad supported and primarily seen on YouTube, producing three of the new YouTube content channels as well as elsewhere. Billboard reported one of those channels will be called the Maker Music Network, with the other two focused on content for mothers and Hispanics.

With about 9 million unique U.S. viewers in September, according to comScore, Maker Studios is the fourth most popular YouTube producer after Vevo, Warner Music Group and Machinima. Maker Studios reports having over 28 million subscribers and 400 million monthly views across more than 100 channels.

The Venice, Calif.-based startup has $4 million in total funding from Greycroft Partners and GRP Partners
