TV drama Jericho has been axed by network CBS over its dwindling audience. The series - a portrayal of America post-nuclear attacks - has attracted a small, devoted group of fans, who begged CBS bosses to green light a second series last year after unimpressive viewing figures. Part of their plea involved sending 40,000 pounds of peanuts - a reference to a line of dialogue uttered by the show's actor Skeet Ulrich - to the broadcaster. CBS responded by commissioning seven more episodes - but audience numbers have continued to plummet, forcing the network to make Tuesday's show the last. Spokeswoman Nina Tassler says, "Without question, there are passionate viewers watching this program. We simply wish there were more. We have no regrets bringing the show back for a second try."
