But if it's so bad then why do they keep using TicketMaster? Surely I'm not buying a ticket to a performance only because I can find it on the TicketMaster web page or box office right? They don't really offer anything substantial over the buying experience I can get anywhere else so the monopoly argument is silly (although they do have a good patent portfolio it's not anything can't innovate around).
It's simply because they will take the heat for them when the artists and venues want to tack on extra fees. That is not say TicketMaster's fees are not high but most of the "extra fees" are extras from the venues and performers.
The same goes with Fandango. You think that extra $1 for buying a ticket online Fandangos fee?? Nope. It's the fee for the movie theatre wants.
I've worked in this ticketing industry in a previous startup so I understand the game well. It's not really crazy the stuff that gets pulled.
