Skeet Ulrich (far right) stars in the post-apocalyptic drama

US TV network CBS axed the show last month, triggering a protest that culminated in shipments of nuts being sent to the broadcaster.

"Wow!" said CBS Entertainment President Nina Tassler in a letter to the fans. "You got our attention."

Tassler said seven new episodes of the drama had been ordered, with more to follow if ratings improve.

"We will count on you to rally around the show, to recruit new viewers with the same grass-roots energy, intensity and volume you have displayed in recent weeks," said Tassler.

"PS. Please stop sending us nuts."

'Incredible'

Jericho is set in a Kansas town whose residents have survived a series of nuclear explosions throughout the US.

The show launched last autumn to positive reviews and encouraging ratings.

After it returned from a three-month mid-season break, however, its viewing figures plummeted, prompting CBS to cancel the show.

The decision enraged fans, who started a letter-writing campaign.

After the season finale, in which one of the characters responds to a demand by saying "nuts", protesters also began sending peanuts to CBS offices.

According to the Nuts For Jericho campaign website, about 18,000 kg of nuts were delivered before the network capitulated.

Deals with cast members, including star Skeet Ulrich, had to be completed before CBS could announce its decision.

On hearing of their victory, fans rushed to the website to congratulate each other.

"Holy brazil nuts! Incredible! This is unbelievable!" wrote one.

"Fans, you have done this! CBS, you have done this! We love you!"
