The early days of MTV often were powered by illegal drugs—particularly cocaine, according to the book IWant My MTV: The Uncensored History of the Music Video by Craig Marks and Rob Tannenbaum. Writes Time‘s Jessica Winter, “Line producers would make receipts for drug purchases and file them under craft services. (‘I would always be able to bury at least a quarter ounce of cocaine in there,’ one producer explains.) Cocaine was to the mid-1980s video professional as Adderall or Diet Coke is to the contemporary business executive.” (Time)
