 Prior to the adoption of Jack, WBUF had a history of short-lived and rapidly changing formats (usually failed attempts to challenge other more dominant stations in the market), with the station typically changing formats every two years between 1993 and 2005.Similarly to other Jack FM stations, WBUF has no live disc jockeys, carries no syndicated long-form or short-form programming, and carries no time-sensitive information (such as news, weather or sports), only interrupting its music for commercials, pre-recorded one-line jokes and station identification; this format is followed uniformly, 24 hours a day, 7 days a week.At first, 92.9 was one of the only Jack FM stations which didn't use Howard Cogan as the voice of Jack due to its proximity to Toronto's CJAQ-FM, which identified itself as "92.5 Jack-FM".
