The US Department of Justice antitrust case against Google alleges an illegal monopoly in search and search advertising in their home and largest market.

The low tide of transactions has cemented the reign of Rightmove and condemned challengers to low traction. No. 2 player, Zoopla, plans for a major drive in 2020 after a 1.5-year investment spree by parent private equity firm Silver Lake Partners.
