The company is one of the biggest names in the real estate business you've never heard of. Instead, it operates through the names you have heard of: Century 21, Coldwell Banker, Sotheby's International Realty, and ERA. The company also licenses the Better Homes and Gardens brand from Meredith Corporation. Realogy has nearly 16,000 offices (more than 900 are company-owned) in nearly 90 countries. Besides its bread and butter of residential real estate and corporate relocation, it also offers title settlement and research through Title Resource Group. Domus Holding (an affiliate of Apollo Advisors) acquired Realogy for a reported $9 billion.
