A number of factors were at play, from the show's length to the array of other entertainment options viewers can choose from. It probably didn't help that some of the year's biggest blockbusters like "Avengers: Endgame" didn't win any major awards.
The night's most exclusive after after party belonged, again, to Beyoncé and Jay-Z. The couple hosted their so-secret-we-can't-even-show-you bash at the famed Chateau Marmont.
One lucky guest, Reese Witherspoon, at least revealed she was invited.
"Only @beyonce could get me out of the house past 11pm," Witherspoon captioned a party-ready Instagram post.
The "In Memoriam" segment of last night's Academy Awards caused some viewers grief.
Perry's exclusion was an especially sore spot for some given that he appeared in the Oscar-nominated film, "Once Upon a time... in Hollywood."
CNN has reached out to the Academy comment on how they select who to include in the broadcast tribute.
The film follows two disparate Korean families, one rich and one poor, and all that ensues when the poor family cons its way into the lives of the wealthier one.
Directer Bong Joon Ho is working with American director/producer Adam McKay to bring a limited series to HBO that expands on the film.
HBO is owned by CNN's parent company WarnerMedia.
Phoenix called out the lifestyles of the rich and famous and asked them to reflect on how they contribute to climate change.
"We don't have to take private jets to Palm Springs for the awards sometimes or back, please," he said.
After winning best actor at the awards, Phoenix acknowledge how this is an example of systemic racism in this industry.
"I think we send a very clear message to people of color that you're not welcome here. I think that's the message we're sending to people that have contributed so much to our medium and our industry and in ways that we benefit from," he said in his speech.
After becoming the second performer to win an Oscar for the role of the Joker, Phoenix took a stance against the dairy industry in his acceptance speech.
"We feel entitled to artificially inseminate a cow, and when she gives birth, we steal her baby," Phoenix, a lifelong vegan, told the crowd. "And then we take her milk that's intended for her calf and we put it in our coffee and cereal."
Taika Waititi has become one of the first indigenous New Zealanders to win an Oscar.
He wrote, directed and starred in the film.
"I dedicate this to all the indigenous kids in the world who want to do art and dance and write stories," Waititi said in his acceptance speech. "We are the original storytellers and we can make it here as well."
"I feel like a very opportune moment in history is happening right now," producer Kwak Sin Ae said, via translator.
She wasn't wrong. "Parasite" picked up four awards on Sunday night, including a history-making best picture win.
But those in the audience protested, asking loudly from their seats for the stage directors to turn the lights back up and let Lee speak.
They won, and she got her turn.
In the end, the infectious buzz around the South Korean film, which centers on two families on opposite sides of South Korea's economic gap, turned out to be too powerful for its Oscar competitors, which included some of Hollywood's most seasoned filmmakers.
It also picked up best director, best international feature film and best original screenplay.
Lin-Manuel Miranda introduced a song medley at the 92nd Academy Awards, and it appeared it was just another compilation of songs in movies that have had an impact.
Although those at home seemed torn. Some took to Twitter to praise the performance and some were shaking their heads as to why he was there.
Later, Eminem himself took to Twitter to explain: "Look, if you had another shot, another opportunity... Thanks for having me @The Academy," he wrote, adding, "Sorry it took me 18 years to get here."
In the end, "Parasite" took home the night's top honor and made history.
Here are some of the highlights from last night's show:
