It could have been a good story; the multimillion-dollar global IBM advertising campaign which broke this weekend, axed over the use of the word `bummer’. According to an IBM source, the seemingly harmless caption struck fear into TV watchdogs, who insisted `bummer’ had drug connotations. The Diary called the Broadcast Advertising Clearance Centre offices to find out what on earth they were taking up there. `Sorry to ruin your story but we haven’t got the faintest idea what you’re talking about,’ said the spokesman. The ad does appear with the word, but if anybody can explain the drug connotation the Diary would like to hear from you and how you came across the information.
