Industry insiders say Atlanta, already a hotspot for news, music and tourism, is now a breeding ground for digital media and interactive entertainment companies with creative professionals working in gaming, 3D, animation and even audio books.

"The digital entertainment industry is changing constantly," said Asante Bradford, digital entertainment and interactive media project manager for the Georgia Department of Economic Development. "It has taken off, and we're starting to see a lot of that here with our content creators."

The Georgia Department of Economic Development offers film, television and digital entertainment tax credits of up to 30 percent. With that financial boost leading to more businesses locating and expanding in Atlanta, keep an eye on these five innovative metro-area companies.

Hi-Rez StudiosFounded in 2005, Hi-Rez Studios is helping put Georgia on the gaming industry map.

Released in early 2014, "SMITE" is a multiplayer online battle arena game for Microsoft and Xbox One with millions of registered users worldwide. An even newer game, Paladins is doing well too.

The growth, along with qualifying for state's tax credit, allowed the Alpharetta company to double its full-time salaried staff, grew from 75 to 150 workers in 2015, according to the company. Hi-Rez' website currently lists more than a dozen job descriptions.
