Reality fans helped the networks keep the lights on during the summer, and now, CBS and NBC are thanking viewers by serving up more of the same. The broadcasters announced renewals for ''The Amazing Race,'' ''Big Brother,'' and ''The Restaurant,'' though there'll probably be some changes in all three shows. Even Simon Cowell's ''Cupid,'' though it failed to win as many hearts as the other shows, may be back next year, CBS reality honcho Ghen Maynard told the Hollywood Reporter.
''Race'' has already started casting for its fifth season. Executive producer Bertram van Munster promised ''drastic changes'' when the show returns to CBS, either in midseason or next summer. He declined to specify but said fans ''are going to be in for a big surprise.'' ''Big Brother'' producers, coming off the CBS show's highest-rated season yet, also promised new twists next summer.
It's not clear whether star chef Rocco DiSpirito will still be dishing out drama on NBC's ''Restaurant.'' Coproducer Ben Silverman told the Reporter, ''We're either going to continue working with Rocco -- and there are incredible story lines that haven't yet been dealt with -- or we're going to launch a new 'Restaurant' with a new chef, and we might even do both.''
