"Cinematic exhibition [including 3D rooms] and computer games will cease immediately in whatever kind of private business activity," said the message from the Executive Committee of the Council of Ministers.
Many private cinema operators spent thousands of dollars to launch their businesses, which range from modest to flashy and offer the latest Hollywood blockbusters and fast-paced video games.
"Economically, this really hurts us. This [business] was a relief for the family," said Orlando Suárez, speaking in front of a marquee listing Saturday's entertainment program at his San Rafael 3D cinema in central Havana. "We don't understand why they didn't give us a window of time instead of taking this stance of 'close down now.' "

"It's a lack of respect. What are we going to do now?" asked Lionny González, a 15-year-old high school student. "Now the only thing left for us is to go to a disco. There's nothing else."
"Young people need these [video-game] salons," said Rafael González, a 53-year-old father of five. "They spend time there instead of being on the streets."
Recently the Communist Party youth newspaper Juventud Rebelde published a lengthy article quoting Vice Minister of Culture Fernando Rojas as saying the video salons promote "frivolity, mediocrity, pseudo-culture and banality," raising fears of a crackdown.
Cuba also recently announced a ban on private commercialization of imported goods. Saturday's message said small-business owners who have been selling products brought from overseas will have until Dec. 31 to liquidate their inventories.
