According to the TV ratings Guide, the Oscar telecast drew around 15.6 million viewers last night, give or take.
N.Y. Times reporter Brooks Barnes, 3.13.23: “The 2022 show drew 16.6 million viewers, the second-worst turnout on record after the pandemic-affected 2021 telecast. If the Nielsen ratings do not improve, the Academy of Motion Picture Arts & Sciences faces a financial precipice: Most of its revenue comes from the sale of broadcasting rights to the show. Hundreds of millions of dollars are at stake. The most-viewed Oscars telecast was in 1998, when 57.2 million people watched Titanic win the trophy for best picture.”
