Revelers around the globe are bidding farewell to a decade that will be remembered for the rise of social media, the Arab Spring, the #MeToo movement and, of course, President Donald Trump. A look at how the world is ushering in 2020:
Fireworks burst and confetti fell as throngs of revelers cheered the start of 2020 in New York City's Times Square.
In one of the globe's most-watched New Year's Eve spectacles, the crowd counted down the last seconds of 2019 as a luminescent crystal ball descended down a pole.
About 3,000 pounds (1,360 kilograms) of confetti showered the sea of attendees, many of whom were also briefly rained on earlier in the evening as they waited in security pens for performances by stars including rap-pop star Post Malone, K-pop group BTS, country singer Sam Hunt and singer-songwriter Alanis Morissette.
The crowds packed into the heart of Manhattan mouthed lyrics and waved yellow and purple balloons in a frenzy as midnight approached.
“It was a dream, I wanted to do it so this year a lot of people helped me to get here so I’m here, and I’m thankful for that," said Mariemma Mejias, 48, who flew to New York for the festivities from San Juan, Puerto Rico.
