The big event movies are placed in the summer months to specifically draw in the kids who are out of school. In the past, that's led to a period when the movie industry makes a large chunk of its revenue for the year.

But both studios and exhibitors are suddenly seeing that the game has changed.

Summer movie ticket sales dropped 10% from the previous year in 2016 at the domestic box office. And they were down 12% this summer compared to 2016. The effects can be seen at the country's biggest multiplexes, which saw shares plummet.
