You need to deduct at least 70% (or more) from their topline to get a true picture of the company’s revenue vs revenue that walks straight out the door.
Better to set their margins at 2-3% and keep a monopoly than be forced down in a competitive marketplace.
After all, the idea of competing with Ticketmaster is silly, since the problem isn't originating in Ticketmaster at all, that's where the problem is most visible.
People complaining about Ticketmaster are complaining about Live Nation too. It's just that the Ticketmaster brand gets the heat, because that's how they run the brand.
It's not like Ticketmaster wasn't doing the same stuff when Live Nation was a separate company, or even when Live Nation was a separate company that was doing its own ticketing.
