I mean like on your local TV/radio stations, billboards,... Where the ad would 'simply' explain the concept and its advantages. Could this help to make bitcoin more popular?
YES! because if we talk here there are only a part of people that could understand btc value!
I mean geek, nerd, scammers

and so on....
There are a lot of people that could appreciate btc!
EDIT: Or an even better question: should we try to make bitcoin more popular?
yes we should. like talk with parents, friends, workers and so...
The best way for a strong currency, and regrets bank system!!
