In 1975, Ebert teamed with rival newspaper critic Gene Siskel to co-host a local film-review show that public television picked up for national distribution three years later -- and the dueling twosome turned into a cultural fixture in America. When the program went into commercial syndication in 1982 and was renamed "At the Movies," the duo began using the "thumbs up, thumbs down" rating system that became their trademark.
After Siskel died in 1999, Ebert continued the show with new co-hosts until falling ill in 2002. A series of surgeries to remove malignant tumors left him left him unable to speak, but he carried on his incisive reviews in print until losing his battle with cancer April 4, 2013.
