Roger Ebert fears so. One reason besides the ballooning price of tickets and snacks:
Competition from other forms of delivery. Movies streaming over the internet are no longer a sci-fi fantasy. TV screens are growing larger and cheaper. Consumers are finding devices that easily play internet movies through TV sets. Netflix alone accounts for 30% of all internet traffic in the evening. That represents millions of moviegoers. They're simply not in a theater. This could be seen as an argument about why newspapers and their readers need movie critics more than ever; the number of choices can be baffling.
