Etymology

Origin of mainstream

First recorded in 1660–70; main ¹ + stream

Explanation

Mainstream describes what's viewed by most people in a society as "normal," like the mainstream view that everyone should get married, move to the suburbs, and have children as soon as they can. Something that's mainstream is conventional, or the usual way of doing things. If you're talking about the mainstream in fashion, you mean the ordinary clothes that most people wear and which is found in all the malls — nothing too weird or outlandish. In the 1600s, mainstream described the prevailing current of a river, with the first recorded use of its meaning of prevailing taste or opinion in 1831.
