"Baywatch," once considered the world's most popular TV series, is also the worst American television import ever to hit British screens, according to a magazine survey.

The British TV-industry magazine Broadcast recently asked buyers of foreign programs to name the best and worst U.S. imports. The poll was taken to coincide with the 50th anniversary of the first American show broadcast in the U.K., an episode of "I Love Lucy."

Not surprisingly, "The Simpsons" topped the list of best shows from across the pond. The long-running animated series' cult following in Britain is just as fervid as it is in this country. "Dallas," "24," "M*A*S*H" and "The Larry Sanders Show" round out the top five.

"Baywatch," which ran for 12 seasons in the United States, aired in 140 countries at the height of its run and helped make stars of Pamela Anderson, Yasmine Bleeth and Gina Lee Nolin -- not to mention David Hasselhoff. Broadcast notes the show's popularity but also its " mind-numbing predictability: beachgoer is saved from drowning."

Other shows on the worst list are "The Anna Nicole Show," "The Dukes of Hazzard," "The Jerry Springer Show" and "Manimal."
