why do you think fast-food restaurants became popular?

Simple and it's on the name: fast. People nowadays are always in a hurry and fast foods are that, somewhere you can go and eat without killing much time, and of course the fact that it won't cost too much is also a big factor.

I think alot of it has to do with word of mouth. Alot of it I feels starts by the many americans who live on fast food. They get tired of the same thing to eat everyday. Then we have a new fast food come into town and they go try it in hopes of finding a new place to eat. Then in turn they speak about it amongst friends, family, and co-workers etc.

Fastfoods became so popular because of the change of lifestyle of the people. Even in the workplace, we always value time. Race against the clock. We should finish this before the deadline. And now, problems came up, like "Do we have time for food?" or "Do we have time waiting for our food to be cooked?" And then the answer to this question is fastfood. They system of almost an instant meal hit the consumers because they can insert it to their very tight schedule. Hence, the popularity of the fastfood.
