After more than 40 years and more than 10,000 episodes each filled with daytime drama, ABC announced Thursday that it is canceling both All My Children and One Life to Live. The former soap opera, which has been on the air since 1970, will end in September, and the latter, which began in 1968, will end in January. General Hospital will be the only soap opera remaining in the ABC daytime lineup. In a massive blow to the genre, ABC will replace those two series with Chew, a food program with celebrity chef Mario Batali, and The Revolution, a show featuring health and lifestyle transformations. Project Runway’s Tim Gunn will be one of the hosts.
