What was the London Athletics Meet renamed in 2013?

The London Athletics Meet was renamed the Anniversary Games in 2013.

The name marked the first anniversary of the opening ceremony of the London 2012 Olympic Games. The 2013 event was staged at the Olympic Stadium in Queen Elizabeth Olympic Park, the same venue that had hosted the Olympic athletics competition the previous summer. The Anniversary Games therefore served both as a major athletics meeting and as part of London’s Olympic legacy celebrations.

Before 2013, the event was generally known as the London Grand Prix and was associated with Crystal Palace. After its Olympic Park move, it used several identities, including Anniversary Games and London Diamond League, before adopting London Athletics Meet as its current event name. The anniversary title should not be confused with the London 2012 Olympics themselves.
