Snyder died Sunday in San Francisco from complications associated with leukemia, his longtime producer and friend Mike Horowicz told The Associated Press on Monday.

Known for his improvised, casual style and robust laughter, Snyder conducted a number of memorable interviews as host of NBC's "The Tomorrow Show." Among his guests were John Lennon, Charles Manson and Johnny Rotten of the Sex Pistols.

Snyder began his career as a radio reporter in Milwaukee in the 1960s, then moved into local television news. He anchored newscasts in Philadelphia and Los Angeles before moving to late night.

"He loved the broadcast business," said Marciarose Shestack, who co-anchored a noontime newscast with Snyder at KYW-TV in Philadelphia in the 1960s. "He was very surprising and very irreverent and not at all a typical newscaster."

In 1972, Snyder left news to host "The Tomorrow Show," which followed "The Tonight Show" with Johnny Carson.
