Silvio Santos, a Brazilian media mogul and television personality who built one of the country’s biggest entertainment empires, died on Saturday in São Paulo. He was 93.

His death, in a hospital, was caused by bronchopneumonia related to a case of H1N1 flu this month, according to a statement by SBT, the television channel he owned.

Mr. Santos spent more than six decades in front of the camera. He created and hosted several popular variety shows, including Brazil’s homegrown version of “Who Wants to Be a Millionaire.” His best-known show, “Programa Silvio Santos,” has been on the air since 1963. (His daughter Patrícia became the host in 2021, although he continued to appear occasionally.)

Every Sunday night, viewers watched Mr. Santos shimmy with dancers, hand out prizes to a mostly female audience, and showcase a range of performers, including circus acrobats, drag queens and hypnotists.

“It wasn’t Sunday without Silvio Santos on the television screen,” said Geraldo Alckmin, Brazil’s vice president, who knew Mr. Santos personally. “He would become part of every Brazilian family in this fun, relaxed way.”

A natural showman, Mr. Santos came to be known for his 100-kilowatt smile and his playful interaction with audiences. Dressed sharply in a custom-made suit, he would walk onstage to the tune of a catchy jingle, posing a question to the audience: “Who wants money?” In one of his signature gimmicks, he fashioned paper planes out of cash and launched them into a cheering crowd.
