Above we have logos of the major American exhibitors, at least as they existed in August 2012. As this caption was written at the time, one might have wanted to hold their breath, as one -or two- of the companies represented could have been bought -or otherwise absorbed- by any other company at any moment. This all proved prophetic. The Rave chain was acquired by Cinemark in May 2013. Carmike became an AMC holding in March 2016.
