There are many good reasons why you really want to be in a business with competition. Possibly the most obvious one is that you don't have to explain quite as much what your business is about.

Let's take the Internet for an example. Back in 1994 when the WWW (World Wide Web) first came on the Internet scene, there were far fewer people using the Internet. Those of us on the Internet at that time were accustomed to text only. We chatted with text, we emailed with text, we had forums with text and we had newsgroups (lists) with text. We had pictures too, but they were attached files, not like the brochures that are on the Internet today.
