When Shivaun and Adam Raff's shopping and price comparison website all but vanished from Google's search results just days after launching, the pair began a gruelling legal battle that would end with a landmark judgement and the tech giant receiving a then record fine.European regulators found the search engine guilty of abusing its market dominance by making its own shopping recommendations appear more prominently than rivals' in its search results. Google spent seven years appealing its €2.4bn fine, but eventually lost in September this year.In their first interview since that verdict the Raffs tell Evan Davis the story behind their website - Foundem - and what they learned about big tech, regulation, and themselves during their almost 20-year fight.Evan is joined by:Shivaun and Adam Raff, co-founders, Foundem; Anne Witt, professor of law, EDHEC business school.Credits:President Barack speaking to Kara Swisher, from the technology news website Recode, in February 2015; Joaquín Almunia speaking at a European Commission press conference in February 2014; Margarethe Vestager speaking at a European Commission press conference in June 2017.
