My mom used to have a small, three-legged wooden stool. I don’t remember the stool being used for any reason, just something to set a newspaper or magazine on for a minute.
It was small and thus not sturdy enough to hold anything of weight.
But no matter if it was strong and sturdy, the three-legged stool was no good if something happened to one of the legs. It couldn’t stand on just two.
You’re probably already wondering what a three-legged stool has to do with the newspaper business.
