The brief was to reach 30 to 40-year-old men with 'a genuine blow-out moment in these serious times'. Sony Music Entertainment UK decided to offer them a moment of rock ‘n’ roll escapism at work. Most office workers are subject to a restrictive internet policy which essentially stops them from having fun. Sony Music Entertainment UK decided to raise two fingers to the IT department by including AC/DC’s music in an Excel spreadsheet, a file type allowed through every corporate firewall. Now we just had to make the spreadsheet compelling enough for people to pass it on. To achieve this Sony Music Entertainment UK created the world’s first music video in Excel with the video playing back real time, frame by frame in ASCII.
