Based off of Ngram usage, it'd probably be fair to say that they popularized it at the very least. Nothing new under the sun and all that.
Now not everyone is going to use something just because it was on TV, but it definitely played a role.
- Earliest use: shortening of "Norman".
- Lots of use by the disabled to refer to people who aren't disabled.

Then it started to be used a little bit in the present prevailing sense on the internet in the late 90's. Usage exploded from 2000-2015, rising >10x, and almost all of the current use is in the current form of referring to people derisively for having normal tastes, hobbies, and viewpoints.

> Around the time Urban Dictionary logged the term in 2004, it began circulating through different social groups on the internet. In the late 2000s, it was adopted by cosplayers and anime enthusiasts and used to describe people who liked what they considered basic anime or weren’t as passionate about anime. In 2012 normie gained popularity on the 4chan forums. Through the mid 2010s it was a staple on meme subreddits such as r/memeeconomy, usually accompanied by a Pepe meme. As normie proliferated 4chan, the online subculture of men called incels (involuntary celibate) began using it in conjunction with the term blue-pilled normalfag, which derides a man who spends time on male message boards but still gets dates or has a girlfriend or wife. Blue-pilled normalfag is closely associated with normie, though the latter slang has broader and less offensive uses.
Somehow I doubt it was used this way "commonly" since the 50's, but maybe I'm just crazy.
