The movie theatre industry has been promising a switch to digital for years, but it still hasn’t happened. “Digital cinema promises to slash distribution costs associated with shipping heavy tins of 35-mm prints to thousands of theaters worldwide. That will give cinema owners new choices and flexibility in booking movies and other kinds of entertainment content, like live concerts or sporting events. But cinema owners still worry that the digital equipment might require constant upgrades, be more complicated to operate, or break down more often than what they’ve got in their projection booths today.”
