Roger Ebert became the first film critic to receive the prize in 1975 for his work as the paper's film critic starting in 1967. He held that position until his death in April 2013.
Field Enterprises co-owners Marshall Field V and Ted Field sold the paper to Rupert Murdoch's News Corporation in 1984. This transaction marked an abrupt shift in style, mirroring the New York Post with sensational front pages and a political stance moving markedly to the right.
On the 31st of March 2009, the newspaper filed for bankruptcy protection following years of financial struggles. The Sun-Times unions agreed to concessions paving the way for Jim Tyree to buy the newspaper and its 50 suburban newspapers for $25 million.
