(AP & NBC News) - Roger Ebert, the longtime critic who popularized film criticism with his "thumbs up, thumbs down" reviews in print and on television, has died, the Chicago Sun-Times reported on Thursday. He was 70.
The paper says on its website the Pulitzer Prize-winning film critic died Thursday.
On Wednesday, he had announced on his blog that he was undergoing radiation treatment after a recurrence of cancer.
Ebert was diagnosed with thyroid cancer in 2002 and later had surgery for cancer of the salivary gland. He lost his chin and his ability to speak. But he later resumed writing full-time and eventually even returned to television.
Ebert started as a film critic for the Chicago Sun-Times in 1967. In 1975 he became the first movie reviewer to get the Pulitzer Prize for criticism.
