However, it is important to understand that in many ways, Ticketmaster is a necessary evil. Yes, they do a good job of playing the proverbial "bad guy" role in their own right but often times, they are thrust into that role by the venue or client, who normally sets the price of tickets and the amount of the maligned service fee. Live entertainment tends to be a business that exists on very thin profit margins and a lot of venues depend on the liquidity that Ticketmaster's way of doing business provides. Pardon the unintended pun but Ticketmaster and their clients usually work in concert but the majority of the blame for the exorbitant price of tickets gets placed upon Ticketmaster.
