The decline of cinema figures

The above website states that attendance in the 1940s in the UK was almost 10 times the size it is today. They calaim that the only films to attract decent cinema figures in recent years are thos which rely heavily on special effects or animation, such as Terminator 3 and Tranformers. The average cinema attendance in the 1940's was 1,400,000,000 compared to the 167 million in 2003.
I believe the reason for this is the growing options available to consumers, such as those that come with DVD's. These are becoming more easily to access and cheaper which causes cinema prices to rise. Together, these two effects result in consumers not wanting to go to cinemas.
