Jon Stewart, who hosted the dismally low-rated 2006 Academy Awards ceremonies, has been tapped to host the Oscars on February 24, 2008, the New York Times reported today (Wednesday), citing two unnamed insiders. An official announcement by the Academy of Motion Picture Arts and Sciences is expected to be made later today, the newspaper said. The Stewart-hosted Oscars in 2006 were the second lowest-rated Academy Awards ceremony ever recorded (behind 2003's); viewership was 10 percent below 2005's, hosted by Chris Rock.
