And concert tickets...jesus, if you even have to ask. I can remember paying $25 for good concert tickets (for mainstream bands) just 20 years ago. Today it's crazy what you pay even for tickets to no-name bands' concerts.
I saw Apocalyptica for just $25 a few weeks ago by buying the ticket at the door. What you're likely encountering is Ticketmaster's runabout scam, which after fees turns that '$25 at the door' into $48 or more. They even intentionally put their site into maintenance mode just as new tickets are released and link to a site that has no mention of Ticketmaster, yet is owned by them, which sells the tickets at up to 10x their box-office price.
The tickets themselves haven't gotten more expensive, really to the contrary, but the fees and greed of the company who monopolizes them has indeed gotten out of hand.
