In 2010, when the National Association of Theatre Owners (NATO) decided to rebrand and move its annual convention (then called ShoWest) from its previous home at Paris and Ballys Hotel in Las Vegas across the street to Caesars Palace they had to come up with solutions for a number of tricky logistics. Would there be enough hotel rooms for delegates and industry professionals? Would it be possible to split the trade show between two different floors? And was there an auditorium large enough at Caesars for studios to present their showreels to attendees during the course of the event? These are just a few of the questions NATO had to answer before the first CinemaCon could take place.
