A holodeck theater was an establishment where people could get together in an holodeck, loading a common holographic program in it, sometimes for a fee. They were, in essence, similar to movie theaters of Ancient Earth, with Kartika Supermall having one, like several Lyran shopping malls. (Star Trek: The Stoneship Files: "Dilithium Dance") Holodeck theaters could contain as little as one holosuite or be organized in megaplexes containing dozens of holodecks. The largest Lyran holodeck theater operators were headquartered on Malachor V. (Star Trek: The Stoneship Files: "The Defector")
