Ebert and Chicago Tribune critic Gene Siskel helped make nationally-televised movie reviewing popular. They co-hosted the PBS show "Sneak Previews". It was followed by "At the Movies" which made both of them popular across the country. The two fought and made jokes while talking about movies. They created and trademarked the phrase "Two Thumbs Up," used when both hosts thought the same movie was very good. After Siskel died in 1999, Ebert continued hosting the show with various co-hosts and then, starting in 2000, with Richard Roeper.
