Heck, no. I read a great deal -- books, newspapers, magazines or the internet, or just plain talk to people.
Last year (?), a piece in The Wall St. Journal mentioned that studio execs claim that the "average" movie (however defined) only makes 30% of its take at the boxoffice. About 40% comes from DVDs, 15% from pay TV and the remaining 15% from other sources such as network TV. Just a few days ago I read somewhere that about 80% of Hollywood's revenues comes from DVDs and TV.
The majority of moviegoers are young men, so, not surprisingly, the studios cater to that demographic: they like loud, stupid and violent films. People who are 30+ have lose the habit of going to the movies and simply wait for the DVD or video to be released. I recently read somewhere that DVDs, unlike videos, are priced to sell and not to rent.
I wonder if that take can be broken down to only movies shown theatrically. It should be broken down to theatrically shown movies and straight to Skinemax movies.
