The research is in, and it says that people love funny cat videos.

The not-so-surprising finding is part of new report about online video from theĀ Pew Research Center's Internet & American Life Project.

Thanks to all the video camera-equipped devices we carry today and the popularity of social networking and video-sharing sites like Facebook, YouTube and Vine, it's become increasingly easy for users to share videos.

Today, the percent of American adult Internet users who post videos online has more than doubled to 31 percent from 14 percent in 2009.

The percent who watch or download videos also has increased to 78 percent today from 69 percent in 2009.

Humorous videos, especially those involving cats and babies, are the most-viewed type, with 58 percent of adult Web users saying it's the genre they favor.

"How-to" videos are the second most popular, followed by educational videos and music videos.

Typically, the videos adult Internet users post are of family and friends "doing everyday things," videos of themselves "doing funny things" or videos of events they attended.

According to the Pew research, 71 percent of adults who post videos online do so using social networking sites, and only 5 percent of users who have posted a video online say "they have regretted a video they have posted in the past."
