The standard format was that the viewer's letter, which described their wish, would be shown on the screen and read out aloud, initially by Savile, but in later series by the viewers themselves as a voice-over. Savile would then introduce the Fix, which would either have been pre-filmed on location or take place "live" in the studio. At the end, the viewer would join Savile to be congratulated and presented with a large medal with the words "Jim Fixed It For Me" engraved on it. Occasionally, other people featured in the "Fix It" (actors from well known series, for example), might also give the viewer an extra gift somehow relating to the Fix. Savile himself played no part in the filming or recording of the "fix-its", unless specifically requested as part of the letter writer's wish. Some children apparently thought that Savile's first name was "Jim'll", so some letters shown on the programme started "Dear Jim'll". Early series saw Savile distributing medals from a "magic chair" which concealed the medals in a variety of compartments. The "magic chair" was invented by Tony Novissimo and was built for the BBC by him at his workshops in
Shepherd's Bush. The chair had first appeared on Savile's earlier Saturday night TV series,
Clunk, Click. The chair was later replaced by a new computer-controlled robotic "magic chair", the brainchild of
Kevin Warwick, built for the BBC by his team at the
University of Reading. The arm for the chair was an RTX robotic arm, Internally, the BBC were concerned that the show was providing excessive product placement for corporations. ==Notable "Fix-its"==
