where can I find some good communications ads?

Answer 1

Your question is incomplete.

"Communications" today has many applications.

Also, are you talking about ads addressing consumer or industrial marketplaces?

Conversly, do you mean you want to know about ads that communicate well? In that case you should also explain more of what you mean by that.

Do you mean print, radio, television, outdoor, Internet or ads in other media?

finally, what is the effective value of the word "good"?

Honestly, I suggest you think more about your terminology, design an effective question, post it and withdraw this one.

Otherwise go look up the web sites for ADWEEK and AD AGE magazines. Each week they publish some of the latest ads in many categories.
