The recent release of the Beatles catalog on iTunes made me think - what did a ticket to see them at their live peak cost?
Answer: a prime seat to see the Beatles in Chicago 1966 cost $5.75 - in today’s dollars this is $37.60 - almost ten times less than what you would pay for a huge act today.
Things were different then of course - touring was done mainly to promote record sales and tickets were priced below market purposely to make sure shows were safely sold out and to reward fans for their record-buying loyalty. This produced what economists call a consumer surplus. Some of that surplus was soaked up by the secondary ticketing market.
