And here are the biggest and buzziest moments:

1. Chris Rock's fiery opening monologue

The controversy over the lack of diversity in this year's Oscar nominees overshadowed the Oscars themselves, and many hoped host Chris Rock would address the issue during the show. He didn't disappoint:

"Is Hollywood racist?" asked Rock in the midst of his pointed, fiery opening monologue. "Is it burning cross racist? No. Is it 'Fetch me some lemonade' racist? No. It's a different type of racist. [...] You're damn right Hollywood is racist. Hollywood is sorority racist. It's like, 'We like you, Rhonda. But you're not a Kappa.'"

"It's not about boycotting anything. We want opportunity. We want the black actors to get the same opportunities. That's it! And not just once. Leo gets a great part every year. What about Jamie Foxx?"

2. Academy President Cheryl Boone Isaacs challenges Oscar attendees to push for diversity

Chris Rock wasn't the only person channeling the #OscarsSoWhite controversy. Academy President Cheryl Boone Isaacs took the stage to challenge the industry to "talk about the future" of Hollywood. "The Oscars celebrate the storytellers who have the opportunity to work in the powerful medium of film, and with that opportunity comes responsibility," she said. "We have a role to play in bringing about vital changes the industry needs so we can accurately reflect the world today."

3. Lady Gaga's stunning "Til It Happens to You" performance

Following an introduction from Vice President Joe Biden, Lady Gaga took the stage to perform the Oscar-nominated song "Til It Happens to You" from the documentary The Hunting Ground, which chronicles incidences of sexual assault on college campuses. As Gaga performed, she was joined by a group of sexual assault survivors, with phrases like "SURVIVOR" and "NOT YOUR FAULT" written on their arms in black marker:

4. Leonardo DiCaprio finally wins his Oscar

Five-time nominee Leonardo DiCaprio finally won his first Oscar, for his lead performance in The Revenant. DiCaprio, who was first nominated all the way back in 1994 for What's Eating Gilbert Grape?, received a standing ovation. He used his acceptance speech to highlight the dangers of climate change.

5. Spotlight upsets The Revenant in Best Picture victory

In a surprise upset that defied the predictions of many Oscar prognosticators — including this oneSpotlight won Best Picture, topping the widely favored frontier drama The Revenant. But don't feel too bad for The Revenant; its director, Alejandro G. Iñárritu, also won his second consecutive Best Director trophy, after winning his first for last year's Birdman.
