Programming an audience

Good day to you sir

I've heard a lot of old time bookers say that when they came into a new territory or starting their allotted stint in a territory, the first thing they would have to do (besides bringing in their crew) would be to program/train the audience to like their specific style of booking. 

How long do you reckon it would take to reprogram an audience today? 

Hope you have a great day

Heyman was trying it but the problem was that there was no audience to program!
