December 31, 1993. Retrieved June 8, 2011. "This week’s issue date broke the usual pattern of Saturday week-ending dates (Dec. 31, 1993, was a Friday). The reason for this might have been that this week’s issue contained the year-end charts and Cash Box wanted to have a 1993 date on its year-end issue."
