Last year's Academy Awards (now The Oscars) created a bit of hub bub by expanding the number of Best Picture nominees from 5 to 10 in hopes of reviving the show's declining TV viewership. The viewership did bounce back to a five year high of 41.699 million, but anyone that attributes that to the 5 extra best picture nominees is kidding themselves. The increased viewership was all about Avatar (even though it didn't win Best Picture).
The Academy Awards is still one of the biggest viewership events in television, and it held up far better than most long running events until the turn of the 21st century. But a variety of changes in the last 10 years seem to have taken their toll, including shifting the broadcast from Monday at 9pm to Sunday at 8:30pm in 1999. 2008's show during the TV writers strike, at just over 32 million viewers, was the least viewed ever.
Since two of the relatively recent Academy Awards viewership peaks were the two times James Cameron had "the highest grossing motion picture in history" in the running (Titanic, 1998; Avatar, 2010), and none of the current year's movies has even remotely the same level of box office success, I'd be surprised if we didn't see a decrease in the viewership towards the recent decline trendline. I'll guess something in the 36-38 million average viewer range.
What's your guess?
