These listings are databases that show residential real estate for sale in regions across the country. The change allegedly caused views on REX's listings to decrease significantly. REX sought to question Mr Barton about Zillow's decision to join multiple listing services and its move to buy houses and originate mortgages. Zillow reported $2 billion in revenue last year. Zillow and NAR have both denied liability and are contesting the claims in the lawsuit. Lawyers for Zillow dispute there was any agreement with NAR and deny that the website redesign harmed competition. Zillow's vice president of industry development has a deposition scheduled later this month. The complaint is seeking unspecified monetary damages and an injunction "from continuing to engage in any anticompetitive conduct". A Zillow spokesperson declined to comment on the pending case, and a representative from NAR had no immediate comment, Reuters said.
