2020 marks the 100th anniversary of the founding of Boxoffice Pro. Though the publication you hold in your hands has had different owners, headquarters, and even names—it was founded in Kansas City by 18-year-old Ben Shlyen as The Reel Journal, then called Boxoffice in 1933 and, more recently, Boxoffice Pro—it has always remained committed to theatrical exhibition.
