"Despacito," the most watched YouTube video ever.

A study from the Pew Research Center has delved into how we use and interact with the world's biggest video site - YouTube.

As well as looking at how people use YouTube, it also examined how YouTube influences people through its algorithm, which recommends videos in the "Up next" section.

Pew compiled a list of the 50 most recommended videos on YouTube. They did this using "random walks" through the video site.

This meant selecting videos at random from English-language channels with more than 250,000 subscribers, before moving on to the recommended videos five times each. The study conducted more than 170,000 of these "walks." You can check out the full methodology here.

Recurring themes are auditions for shows like "The Voice" and "America's Got Talent," music videos, and life hack videos.
