LOS ANGELES, Jan. 18, 2013 (GLOBE NEWSWIRE) -- CoStar Group's LoopNet.com, the #1 marketplace for commercial real estate online, made history Thursday night when a 12-story building in downtown Los Angeles vanished before a live audience as part of a national marketing campaign supporting its Premium Lister product. The event demonstrates that if a property isn't advertised with a premium listing on LoopNet.com, it might as well be invisible. "With more than 6.5 million registered members and 3.5 million unique monthly visitors, LoopNet.com is the premier tool for effectively marketing commercial real estate online," stated CoStar Group Founder and CEO Andrew C. Florance. "Premium Lister leverages LoopNet.com's powerful online marketing platform and gives commercial real estate brokers and owners broad exposure for their listings, access to leads lists, and advanced marketing capabilities." In addition to the stunning visual effect, the event featured a live performance by the Grammy® Award-winning band, Train, which performed two sets before an audience of more than 700 CoStar clients and guests. In addition, CoStar partnered with the band on several charitable initiatives, making $10,000 donations to two charities, Family House and Little Kids Rock. CoStar also will donate a guitar autographed by Train to a local music school in support of Train's commitment to music education. Family House is a 501(c) (3) not-for-profit organization that provides temporary housing to families of seriously ill children receiving treatment at the University of California San Francisco Benioff Children's Hospital. Little Kids Rock is an organization that provides free musical instruments and music instruction to underserved schools across the country. A video of the event is available online here. The multi-channel marketing campaign for Premium Lister was developed by Creative i, a Palo Alto-based integrated communications firm. Cutting-edge, 3D projection technology was used to create the illusion, emphasizing the lack of visibility for properties marketed without LoopNet.com. The technology was developed by Pearl Media, a non-traditional out-of-home media and content company with a client roster that includes Lexus, Chevy, THQ and Twentieth Century Fox Home Entertainment.
