Because the WCD and the Bradley Center were in competition with each other, and it was the WCD that was making the move.
Also, at the time that they did that renovation, there was another reason.... I don't remember exactly who, it was either the people who own the Riverside, Pabst, PAC or Bradley Center that was putting together plans to develop a 4,000 seat venue, which would have been in direct competition with the Auditorium - so they beat them to the punch.
It all seems like a bad move now, but when it was done, they did what they felt they had to do to keep up the business.
Back in those days, Milwaukee county owned the PAC, the Pabst was owned by the Pabst Foundation, the Riverside was Privately held, the Arena, Auditorium and Convention Center were owned by the state and run by the WCD and the Bradley Center was owned by the State and run by the BC Board.
They all competed against each other. Acts would come to down, bid them against each other and Milwaukee would lose - every time.
Now the Pabst & Riverside are owned by the Pabst Foundation.
The PAC, Theater, Arena and soon to be new stadium will be run by the WCD which will absorb the BC board.
Things are a lot different than they were 15 years ago. Had there not been five entities working against each other back then, things may look a lot differently than they do now.
