Well, that's me doomed
I work for one of the few remaining independent theatres, and well, we're fucked then, frankly.
Live Nation and Ticketmaster now control the whole process end to end - creating, producing, marketing and selling the show, and at their own venues.
Increasingly we're left out of national advertising for tours; as Live Nation pay for the adverts, they just list all of the venues and a single Ticketmaster phone number and website. When we point out that customers won't find us on the Ticketmaster website and will book somewhere else, they just shrug and say there isn't room to advertise our own website.
The only solution presented to us is to offer some or all tickets through Ticketmaster, which they often contractually force us to. We make little or no revenue on these tickets (as the theatre really only gets any money from our own booking fee, not the ticket face value), and the customer is screwed too due to massive Ticketmaster ticket fees.
Live Nation is a soulless corporate entity which cares nothing for artistic value. We are merely a small charity they can stomp all over.
