Here’s a clear picture on how billboard advertising is moving on from being just a poster advert on the side of a highway to the one of the most exciting ways to involve consumers in your ads:

Google, Verizon, Reuters, and R/GA have teamed up to take over the largest displays on Times Square that will allow for a giant Google Search by voice experiment/Droid advertisement.

On Black Friday, anyone who calls 888-376-4336 and does a Google Search by voice, will see their results displayed on either the Reuters sign or the NASDAQ sign in Times Square, as reported by TechCrunch.

If ask about a new CD, for example,  the display will come up with a giant Google Map of where you can find it.

The activity is part of a big promotion for Droid, the new Android phone built by Verizon and being heavily pushed by Google.

This year has been a great one for billboard advertising. Remember when MasterCard took over the Old Street roundabout billboard in February with a special Valentine’s message?

But what makes Google’s idea so cool is that it is actually getting people to interact, and that is what is key in the new world of advertising.
