Please remember that the availability of electronic means of communications is not to everyone and not everywhere. What you refer to as "old fashioned" means of communications is very widely used to promote awareness of all types an for all purposes: starting with warnings and reminder (don't smoke), going through requests (help find, vote for) and up to classic sales (the corner shop).

The main thing that has changed over the years is the mix - the weight given to each mean of communications. And that really depends on many things such as what you want to market and to whom, where, and when. 

I am a big fan of handing out gifts like promotional calenders and such.  They are cheap to print and your business name is out there being seen for a whole year.
