Each year the number of fast food restaurants in United States grows, for example in in 2004 there were already 201,667 fast food restaurants but now in 2014 there are 236,333 which is 34,666 more. If you calculate, in 2018 there will be 247,191 of them. There is nothing bad about that, but it means that people buy this food more and that's bad. Fast food companies make a lot of money from people who buy it and why do they do that? It's cheap, tastes and looks good and unhealthy but nobody cares until something happens, a lot of things happen to your body but by the time you note that you will be addicted to chemicals in this food. So in 2013 fast food brands generated a revenue of 13.08 billion U.S. dollars when one burger combo costs about 5 dollars which means there were sold nerly 2600000000000 fast foods.
