Today, most people are more likely to watch their favorite videos online--which is bad news for American television's viewership numbers.

Global YouTube viewers are watching more than 1 billion hours of video a day, according to a new report from the Google-owned video-sharing website. Last year, it saw a 10-fold increase from 2012--when it began using artificial intelligence to create customized recommendations for viewers.

"The corpus of content continues to get richer and richer by the minute, and machine-learning algorithms do a better and better job of surfacing the content that an individual user likes," YouTube chief product officer Neal Mohan said in an interview with The Wall Street Journal.

The new technology isn't just beneficial to users who are trying to discover new content, it's also helping burgeoning artists like entertainers and filmmakers promote their work. A growing number of YouTube celebrities have earned multimillion dollar paychecks through the platform. It would take 65 years to watch the new content uploaded to YouTube each day.

Netflix is also seeing high numbers, but is still lagging behind YouTube. In January 2016, the media streaming service said its users watched 116 million hours of video content per day. Netflix, which was available in over 190 countries as of last year, has made a large push for mobile viewing.

Netflix CEO and co-founder Reed Hastings told the crowd at the Mobile World Conference on Monday that he believes people will only watch content on the internet in 10 to 20 years.

"We've seen great mobile usage throughout Africa, the Middle East, Asia--that's been one of the big stories is how much more people live on mobile," he said. "We've always had the ambition to just do some of the best content the world has ever seen, but then to make it available simultaneously, so there is never any delay. It's incredible for us, very satisfying."
