Well, even before the big shift and consolidation being a broadcast personality was very volatile.
Then when new media started to shrink margins that's when corporatism took hold. Centralizing departments, increasing roles (dj also being Music Director etc.) Syndication and sterilizing of the product happened in earnest.
I went from being a midday jock at Hot 103, with locally directed content and autonomy to DJ, Ryan Seacrest Producer, voictracking KX96 in Brandon, QX104 weekend announcer and Assistant Music Director.
Standard was a family company, bought by Astral, a QC corporation, then bought by Bell Megacorp. They rebranded us to Virgin and all music and programming decisions came from Toronto, and were identical to Virgin Toronto, Calgary, Vancouver, etc etc
I got fired and it was time to go.
