Notes,

In all do respect and while I do partly subscribe to the theory that good TV (is that an oxymoron) make that great TV "Screens and Sound"" are keeping people out of clubs. I think you are blaming too much of the non-hiring of bands on TV alone. Case in point club owners, other than sports bars are not putting large screens up in their establishments to entertain their patrons, they are hiring DJ's or single and duo acts for two reasons:

#1. DJs have already proven that you don't need a big band, 4-6 pieces to motivate and entertain a crowd.

#2. Because of #1 their payout is way smaller than paying a larger group.

I may be way off base but to me it's simple economics, they are spending as little as they have to while still pleasing their patrons.
