WASHINGTON, June 6, 2013 (GLOBE NEWSWIRE) -- CoStar Group, Inc. (Nasdaq:CSGP), commercial real estate's leading provider of information, analytics and marketing services, today announced that it received "Best of Show Campaign" honors in the Summit International Awards for a national, integrated marketing campaign supporting its LoopNet Premium Lister product. Combining print, digital and outdoor multi-media, the campaign focused on the theme that if a property isn't advertised with a premium listing on LoopNet.com, it might as well be invisible. The campaign launched in 2012 with a series of direct mail and email communications and online display ads. In January 2013, the campaign culminated with LoopNet's ground-breaking "LA Traffic Jam" event, when a live audience witnessed a stunning visual effect that made a 12-story building in downtown Los Angeles appear to vanish before their eyes. The award-winning marketing campaign was developed by Creative i, a Palo Alto-based integrated communications firm. "Premium Lister leverages LoopNet.com's powerful online marketing platform to help commercial real estate brokers and owners achieve maximum exposure for their listings with tenants and buyers," said CoStar Founder and CEO Andrew C. Florance. "This powerful product is deserving of an equally impactful marketing campaign, and we are thrilled with the results. Receiving this recognition from Summit International is a tremendous honor in addition to the positive response we've received from our clients."
