Microsoft Bing correctly guessed almost every Oscar winner last year - but it didn't do as well this year

In 2015, Microsoft Bing's prediction engine nailed the Academy Awards, guessing 20 out of 24 Oscar winners. The year before that, it did even better, going 21 for 24.

But when the dust settled after the Oscars 2016 awards ceremony, and all the little golden statues had been handed out, Microsoft Bing only guessed 71% of the winners correctly, with 17 out of 24 correct choices.

To Microsoft's credit, Bing correctly guessed most of the big winners, including Leonardo DiCaprio and Brie Larson for the top acting honors.

But upsets like "Spotlight" beating out Bing's favored "The Revenant" for best picture, or Mark Rylance winning over Sylvester Stallone for best supporting actor, dragged down the average. Still, in both of those cases, the actual winner was Bing's second pick.

Here's the full breakdown of how Bing performed at the Oscars:

Bing's biggest whiff of the night: "Ex Machina," Bing's fifth-place choice, managed to win over the favored "Star Wars: The Force Awakens" for visual effects.

So Bing still did pretty okay, even if it failed to account for all the twists and turns of the real Oscars. Looking forward, Microsoft is using the Bing prediction engine to call the results of tomorrow's Super Tuesday day of political caucuses, where it's guessing that Donald Trump and Hillary Clinton will trounce their rivals.
