Glastonbury Cause And Effect.
In order to counter ticket touting/scalping, the recent Glastinbury festival insisted that tickets were only available online and sold under strict rules. They sold out in minutes.
Now the founder Michael Eavis is complaining that, because the young don't have such good internet connections, this led to an audience that was too old and sedate. It's a strange argument.
Indeed while I doubt that they have insufficient internet access, I'm more convinced that teenagers have less access to the £154 that was charged for the three days, or excitement for what was called a bland line-up.
Making 40,000 tickets available via mail applications is unlikely to change that. Causality is rarely as simple as people think. That's why it's called the marketing mix!
