What did olden people do for their entertainment?
This depends on what you mean by "olden people."
If you are talking about 100 years ago, there was no TV and not even radio. But there were relatively modern things such as amusement parks and sports events. Movies were even starting to be available.
If you go back another 50 years, things are a lot different. In those days, most entertainment would have been "homemade." People would sing a lot and/or play musical instruments. People would socialize, sometimes combining that socialization with work as in quilting bees.
So the sorts of entertainment that people enjoyed really depends on how far back you are talking about.
