The majority of people speak of junk/fast food 3 brands of soda, 2, 3 brands of coffee/tea, 2 brnands of tropical fruit ,3 brands of power-drinks, 3 brands of beer,
as nutrition, 2 brands of phone OSs, and it is all crap if not bad for you.
So what is your point?
What is popular is what has been marketed, and it is usually both dominant and a very poor alternative to what it sells for.
