We're only a few days into 2016, but already we can look back at 2015 and think, "Wow, what an incredible year." There were huge milestones in politics, religion, science, pop culture and sports. There were emotional highs that united us all, and there were lows that did the same.
Just think back over the year. The first new "Star Wars" in a generation has been breaking worldwide box office records. And Adele's "25" reminded the music industry that many millions of people will still pay for music.
Pope Francis made his first trip to the United States, and NASA discovered water 34 million miles away, on Mars. Terrorists killed innocent people on the streets of Paris, and the 2016 U.S. presidential race turned into a battle between a reality TV star, Donald Trump, and the first woman to likely win her party's nomination, Hillary Clinton.
Same-sex marriage became legal, and Caitlyn Jenner left "The Kardashians" to become the most visible transgendered person in history. In a year with so much happening, you can only imagine which stories were the most talked about. One way to find out is with Google Trends. It's a comprehensive list of the most popular online searches of the year.
Note: Google Trends doesn't report on the most-searched words or phrases. It ranks the stories that had the most impact on people, based on the popularity of the search and its percentage of all searches over a period of time.
