The formation of the Fédération Internationale du Sport Automobile (FISA) during 1979 set off the FISA–FOCA controversy, during which FISA and its president Jean-Marie Balestre disputed repeatedly with FOCA over television revenues and technical regulations. "The Guardian" said of FOCA that Ecclestone and Max Mosley "used it to wage a guerrilla war with a very long-term aim in view". FOCA threatened to establish a rival series, boycotted a Grand Prix and FISA withdrew its sanction from races. The result was the 1981 Concorde Agreement, which guaranteed technical stability, as teams were to be given reasonable notice of new regulations. Although FISA asserted its right to the TV revenues, it handed the administration of those rights to FOCA.
