The National Association of REALTORS and Realtor.com have announced a joint media blitz campaign, including national television and radio advertisements. The goal is to combine the influence of each to reach a far broader audience than before. The campaign will promote REALTORS and Realtor.com as the optimal sources for "timely, accurate and comprehensive information and sound, trusted advice."

Zillow and Trulia, which have overtaken Realtor.com as the leading national real estate search portals, are also conducting national marketing campaigns to grown their consumer audience.
