History.
Early history and public listing.
Realtor.com first launched in 1995 as the Realtor Information Network (RIN), which at that time was a closed network providing proprietary information to members of NAR. In 1996, the hosting site became public, allowing any Internet users to search for property listings, and expanded with the addition of Regional Multiple Listing Service (RMLS) listings in August. RIN grew from 32,000 property listings in December 1995 to nearly 400,000 properties by October 1996.
The site was relaunched with the name "Spot Realtor.com" at the same <samp>realtor.com</samp> domain name in November 1996. The site's management was assumed by a company called RealSelect, in a new partnership with NAR, funded by investment from venture capital firms. RealSelect later changed its name to Homestore, and continued to operate the realtor.com site with NAR as a partner.
Starting in 1997, Realtor.com became the exclusive online real estate listings source for several companies, including "USA Today", NBC, and America Online (AOL). Realtor.com also entered into a partnership with Better Homes and Gardens Real Estate Service, beginning in 1998. With more than 1.3 million listings by 1999, Realtor.com had become the largest website for real estate listings, and expanded services to include virtual tours of properties.
Homestore went public in August 1999, raising $140 million in the process. NAR retained a significant equity position, but Homestore negotiated agreements with multiple listing services and brokerages to secure direct feeds of listings.
