My folks were telling me that when they were younger, if they wanted to buy tickets to a sports event, or to a music concert, they had to physically go to the box office of the sports arena, or to the theatre where the concert was going to be held, to buy the tickets. This was a major inconvenience for them because they lived quite a distance away from where the event was, and this meant that they had to make two long distance trips to get to the event that they wanted to go to see.
For example, my mother said that she wanted to go see the Rolling Stones in concert on the July 4, 1972 concert in Washington DC, but she lived over an hour away from arena. She had to go to the arena a month before the concert (she got lost trying to get there and ended up getting lost in “the bad section of town” and was scared witless) to buy the tickets. This was before the subway train (now in existence called Metro) had been built and she was forced to try to find it by driving. So driving there and parking was a big issue.
It’s hard to imagine how hard it was back then to buy tickets to an event because now it is so easy to buy tickets over the phone and over the Internet.
