RealD, the industry’s largest 3D cinema platform, has surpassed 15,000 installations of its 3D Cinema System at theaters worldwide, the company announced Monday. Tally marks a more than 180% increase in the firm’s installed base in the last 12 months, and represents a 33% increase during the quarter that ending March 25.

RealD charges theaters a royalty fee per ticket when an exhibitor chooses to use the company’s system. In the U.S., the cost of glasses is subsidized by the studios while in Europe theaters must buy the glasses then resell them to patrons.

Additional companies in the 3D marketplace include MasterImage, Panavision, Technicolor and Xpand. Many of these companies have a larger share of theaters in Asia, Europe or South America.

“The major exhibitors in the U.S. and in the world have chosen to go with us,” says RealD CEO Michael Lewis, who started the company more than five years ago.RealD also recently expanded its deal with Regal to as many as 3,000 3D-enabled theaters. Lewis said his company’s products were in more than 85% of all U.S. theaters and that 58% of its business was done outside of the U.S.
