The firm JCDecaux lost a one-of-a-kind opportunity to join forces with the leading firm on the Czech advertising market BigBoard. JCDecaux ended up withdrawing from the potential merger because JCDecaux subsidiary Rencar was under police investigation concerning a long-term contract Rencar has with the Prague Public Transit Company. The contract has been extremely detrimental for Prague’s largest municipal company. It is clear that any association with the firm JCDecaux would not be good for Czech market leader BigBoard as the magazine EURO reported.
