RIP: Hugh Downs, longtime TV personality, dead at 99. “In 1985, Downs was certified by the Guinness Book of World Records as holding the record for the most hours on network commercial television (over 15,000) — a record that stood until it was broken by Regis Philbin in 2004.”

UPDATE (FROM GLENN): I was on the National Space Society board with him in the nineties. Terrific guy.
