Twitter users fired off 36.4 million messages during the 83rd Academy Awards, about two million fewer than during last month's Super Bowl.
"This was a huge event, with a huge conversation happening around it - not in sharp spikes, but in a broad, sustained surge," the San Francisco-based Twitter said in a blog post.
Twitter said users of the micro-blogging service tapped out 38.5 million tweets during the Feb 7 Super Bowl won by the Green Bay Packers.
Among those tweeting on Sunday night at the Oscars was co-host James Franco, star of "127 Hours."
Franco's account, @jamesfranco, was mentioned 63,737 times on Twitter during the show, Twitter said.
