Ratings for Sunday night's Oscars telecast on ABC were delayed by Nielsen Media Research today (Monday), but preliminary results suggested that the telecast may have wound up as the least-watched in history. Nielsen said that preliminary results from 56 markets indicated that that the show had averaged a 21.9 rating and a 33 share, which would put the total audience at around 29 million. The 2003 telecast, which occurred during the U.S. invasion of Iraq, produced the lowest audience to date -- about 33 million.
