I didn't see this mentioned in the thread earlier, but I thought that movie theater attendance was interesting in terms of minimum wage. When I was a kid, minimum wage for 1 hour of work was more than the cost of a movie ticket. Now, minimum wage is significantly less than the price of a movie ticket.
Likewise, I started thinking about the cost of popcorn. As a kid, spending my hard earned money from my paper route, and later, minimum wage work in a kitchen, I cannot remember balking at the price of popcorn. A bag of popcorn and a soda certainly didn't approach the cost of the ticket back then, or at least I didn't think it did. So, I did a little research - seems my memory is just fine. I think tickets were about $3 back then, and popcorn and soda around 50 cents each. So, I researched it to see if my memory served me correctly; it did.

Popcorn has far outpaced inflation. Ditto movie ticket prices. It would seem that as a percentage of a middle class family's income, the cost for a family of four to attend one movie, including refreshments, has significantly increased. Is it any wonder then that the amount of trips to the theater has dropped? Especially last year, given the economy??
And lastly, the movie companies are simply playing that kids' game: Lemonade Stand - figuring out what level to set the prices for maximum profit; not for maximum viewership of their movies. If they're claiming incredulity at falling viewership, they're not being genuine. It's a numbers game - raise prices, lose some viewers, but make more profit. And, given that a lot of movies are steaming piles of crap that the movie companies know people will flock to regardless, simply because of who is starring in it (face it; someone out there must like Nicolas Cage movies), or the title of the movie.
