Movie theaters have struggled to explain significantly lower attendance rates that have plagued the industry this year. Let's take a look at some of the proposed explanations.

Ticket prices, while mind-blowingly high, did not deter moviegoers in the start or middle of the economic slowdown that began in 2008. In fact, escapism helped bring an increase in movie attendance. Ticket prices have gradually increased in the years since 2008 but hardly enough to explain a 6% year-to-date drop in attendance.

How about home entertainment? Flat screens and high-definition surround-sound speakers have been getting bigger and cheaper every year. It's no longer a bank-busting endeavor to outfit a living room with theater-like sound and picture quality. Even 3-D televisions have hit the market, allowing consumers to add that final modern-viewing touch.

Perhaps this is the cause, but sales of plasma and LCD flat screens have been up for years, and 3-D sets haven't exactly been flying off the shelves, so why would the effects only be seen now?

As for content, Rick Aristotle Munarriz of The Motley Fool writes "This is the year, after all, in which we got the eighth and final installment in the Harry Potter movie series. Other popular franchises -- Transformers, Cars, Pirates of the Caribbean, The Hangover -- kicked in with fresh sequels." How could such cash-cow blockbusters fail to bridge an attendance gap?

And as for content to play on home entertainment systems, the bridge between movie and DVD releases has been growing shorter every year. Services like On Demand, Netflix, and Hulu offer a wide range of film and television options.

Still, "streaming services such as Netflix and Hulu have also been more popular for television shows than movies, largely because studios aren't allowing their freshest retail releases to be made available on all-you-can-stream websites."

One explanation that hasn't been offered is a drop-off at the concession stand -- a serious profit driver for theaters. Are consumers still as willing to pay $4 or more for soda as they were in pre-recession days? And perhaps the content just isn't what it used to be to convince moviegoers they simply can't wait for it to hit DVDs, and that transportation, ticket prices, 3-D fees, and concession prices are all worth the trip.
