"Genuinely interested to know what is keeping a nimble new startup from stepping in and blowing this up." I work at a nimble startup so I can tell you exactly why we haven't been able to secure a lot of Ticketmaster's clients. They are part of a very large umbrella corporation that also owns booking agencies for popular international artists. So when a venue decides to ditch Ticketmaster, they will be instantly unable to book any big names that are almost guaranteed to get sold out. https://en.wikipedia.org/wiki/Live_Nation_(events_promoter) https://en.wikipedia.org/wiki/Live_Nation_(events_promoter) This is one of the most important reasons most of our clients are independent event organizers that will never book mega stars. Nimble new startups will have to take the market from the bottom up.
