In a development as depressing as it is unsurprising, movie studios are increasing eschewing print advertising in newspapers for their new movies.
The LA Times has a piece about the trend here.
You can see the effect locally. In looking at the movie listings in today's Go! section in the Star, I noticed that the AMC theater chain does not have any ad. For awhile they were running a shortened ad that didn't list the individual theaters and showtimes, but simply directed you to their web site for a schedule. Now it's missing completely.
