In 2001, Fuller, Cowell, and TV producer Simon Jones attempted to sell the Pop Idol format to the United States, but the idea was initially met with poor responses from all the television networks including Fox. However, Rupert Murdoch, head of Fox's parent company, was later persuaded to buy the series by his daughter, Elisabeth, who had seen the British show. Although Fox's executives wanted to change the format, Murdoch insisted that it should remain the same as the British one. One change was nevertheless made due to the presence of multiple time zones in the United States that made it impractical for the country to vote in the same time period, an additional half-hour results show was therefore added the day following the performance show. The show was renamed American Idol: The Search for a Superstar and debuted in the summer of 2002. Cowell was initially offered the job of showrunner, but turned down the offer; Lythgoe then took over that position. Much to the surprise of Cowell and Fox, it became one of the biggest shows of the summer. With its successful launch in the summer, the show was then moved to January and expanded. The show grew into a phenomenon largely due to its personal engagement with the contestants by prompting the viewers to vote, and the presence of the acid-tongued Cowell as a judge. By 2004, it had become the most-watched show on U. S. television, a position it then held for seven consecutive seasons.
