The Kickoff Curse, I'm somewhat proud to say, is one of my own long-standing statistical discoveries. Basically, it's a predictor of failure, warning that the first new prime-time series to be broadcast each season is likely to die before embarking on a second season.

The idea of giving early starts to shows before the official launch of a TV season began in 1975, with aggressive CBS Chairman William S. Paley. He was so insistent on giving every opportunity to promote his pet project that year, an American equivalent of Upstairs, Downstairs called Beacon Hill, that he launched it a month early -- and launched a comedy series, Big Eddie, even earlier. Even though Beacon Hill starred Edward Herrmann and future Sopranos matriarch Nancy Marchand, both shows died quickly, and the Kickoff Curse was born.

The very next year, in 1976, CBS tried again, and this time succeeded: Its sitcom Alice, a spinoff of the movie Alice Doesn't Live Here Anymore, lasted for nine seasons. But it would be 13 years before another series would survive the Kickoff Curse. That show, ABC's Primetime Live, is still alive, though no longer Live.)

Since then, the curse has claimed all but four early-bird new series: the 1991 sitcom Roc (three seasons), the 2000 sitcom Girlfriends (which began on and outlived UPN, and was recently canceled by the CW), the 2001 sitcom One on One (five seasons on UPN), and, most recently, the Fox drama Prison Break, which premiered in 2005 and begins its fourth season Sept. 1.

Other than that, it's been all flops -- whether the shows have been terrific, like 1994's My So-Called Life, introducing Claire Danes, or terrible, like 1983's We Got It Made, introducing Teri Copley. (Exactly.) In 33 years, only six shows have managed to escape the Kickoff Curse. That's a predictor of failure of 82 percent, with over three decades of test samples.

So if America's Toughest Jobs doesn't return for a second season in 2009, remember: You heard it here first. That series is, in a word, cursed.

For the record, here's a total rundown of the shows falling victim to, or defying, the Kickoff Curse. Shows in bold italics, preceded by asterisks, are the only ones to have survived more than a season.
