Television’s longest-running variety show is calling it a wrap after 53 years.

The Miami-based Univision network said Friday the popular Sábado Gigante will end its weekly broadcast on 19 September.

Created by its Chilean-born host, the boisterous presenter with a huge grin known as Don Francisco, the weekly three-hour show Sábado Gigante has long been Univision’s most popular program.

With an average of 2.2 million viewers, the show remains No 1 on Saturday nights among Hispanics in the US and was up this season among younger viewers, according to the Nielson company. The show also is broadcast to more than a dozen countries throughout Latin America.

Univision did not say why it was ending Sábado Gigante, nor what kind of programming will fill its slot. The network said Don Francisco, whose real name is Mario Kreutzberger, will continue to work on special programs and a telethon that has raised hundreds of millions of dollars over the years to benefit disabled children.

The details of the decision will be revealed by Kreutzberger on the broadcast this Saturday, according to a network spokesperson who was not authorized to be quoted by name.

Sábado Gigante, which means Giant Saturday in English, aired for the first time in Chile in 1962, and moved to Miami in 1986.

The variety show mixing humor, amateur talent contests, celebrity interviews and human-interest stories went on to become a weekly staple for many Hispanic families in the US, sometimes with several generations gathered around the television set on Saturday evenings.

Guests have included Hispanic artists such as Enrique Iglesias, Shakira, Paulina Rubio and Gloria Trevi, and US presidents George W Bush and Barack Obama. Latin American politicians also have appeared on the program.

In a release from the network, Alberto Ciurana, president of programming and content for Univision Communications Inc, called the 74-year-old Kreutzberger “one of the most beloved and legendary entertainers in the world” and an “innovative and inspirational force in the television industry throughout his career”.

“We join Mario’s fans in wishing him all the best as he enters his next chapter,” Ciurana said.

Kreutzberger, who long has divided his time between Chile and Miami to produce the program, thanked the show’s viewers for their “support, loyalty and enthusiasm”.

He said his fans had “allowed the show to become an unprecedented success in the history of this medium”.
