So this is why we have to watch 15 minutes of ads before they show the movie.

Revenue from advertising shown on movie-theater screens rose 20.6 percent to $527.8 million in 2005, the Cinema Advertising Council said Monday.

Pre-Trailer Ads in Movies Producing Big Revenue for Theaters

And that’s not all. Theaters also report approximately $75 million in revenue for other ads.

I still can’t figure out why tickets cost so much they seem to be generating profit from all sides. They’re definitely not paying all of that money to the counter workers.

Let’s put this in perspective.  In 2006 the number 2 and 3 grossing films (Harry Potter and the Goblet of Fire and The Chronicles of Narnia) made a combined $580 million domestically.  This about equals the revenue generated from the ads shown prior to all movies in 2005.  In 2006 Sin City made $75 million in domestic box office this about equals the profits from other ad sources.
