CH this is the main regards the Concorde Agreement :
The Concorde Agreement is a contract between the Fédération Internationale de l'Automobile (FIA), the Formula One teams and the Formula One Administration. The Concorde Agreement defines the agreement about how the teams race, and how the money is divided up. The money includes the television revenue and prize money.
There have been six Concorde Agreements since 1981. The terms of all of the agreements have been kept a secret. The secrecy was broken by racing journalist Forrest Bond when the 1997 Concorde Agreement was published in 2006 by RaceFax.
The basic requirements of the agreements are to be professional and to increase the success of Formula One. The biggest requirement of the teams to participate in every race. This makes Formula One better for the broadcasters. Broadcasters spend a large amount of money to televise the races. In return for racing, the teams were guaranteed a percentage of the sport's revenue.I'm not sure the principles have changed much to date.
Agree re the Grid Girls being re introduced.
