Digital Cinema Distribution Coalition, which distributes digital content to partnered movie theaters via satellite and ground technology, has added Carmike Cinemas Inc., Marcus Theatres and Wehrenberg Theatres to its network.

DCDC’s digital platform replaces the need for studios to ship film reels or hard disks to theaters, making the distribution of films, movie trailers and pre-show commercials more cost-efficient.

The Century City coalition, which launched in October of last year, was formed by theater chains AMC Theatres, Regal Entertainment Group and Cinemark Theatres and studios Universal Pictures and Warner Bros. DCDC’s latest additions bring in a total of 4,000 screens across 300 theaters. Its total reach is now 21,000 screens in 1,800 locations.

“These great theatre operators, as well as our many top content provider customers, are drawn to our state-of-the-art, cost-effective and efficient digital delivery platform and our unique business model, which provides a fair and uniform pricing structure to all of our customers,” said Chief Executive Randy Blotky in a statement.
