Think with Google has crunched the numbers and released a fascinating infographic titled Behind the Box Office.

Some data:

• Of movie goers who use video sites to research films, 4 out of 5 go to Youtube to watch trailers
• The official trailer influences 39%
• Only 8% are swayed by a friend’s opinion

My take: I’m really surprised that word-of-mouth is so low. The graph of views of movie-related content over time is very interesting. Well worth a quick look.
