MrBeast

Jimmy Donaldson, better known by his online alias MrBeast (formerly MrBeast6000), is an American YouTuber, businessman, and philanthropist. He has been credited with pioneering a genre of YouTube videos that center on expensive stunts. He is also the founder of MrBeast Burger and the co-creator of Team Trees, a fundraiser for the Arbor Day Foundation, which has raised over $23 million, and Team Seas, a fundraiser for Ocean Conservancy and The Ocean Cleanup, which aims to raise $30 million by January 1, 2022. He is managed by the Dallas-based talent management company Night Media.

Donaldson began posting videos to YouTube in early 2012 at the age of 13, under the handle "MrBeast6000"; his early content ranged from Let's Plays to "videos estimating the wealth of other YouTubers". He went viral in 2017 after his "counting to 100,000" video earned tens of thousands of views in just a few days, and he has become increasingly popular ever since, with most of his videos gaining tens of millions of views. Over time, his style of content diversified to include challenge and donation videos that reward thousands of dollars, videos either with arduous tasks or survival, and original vlogging videos. Once his channel took off, Donaldson hired several of his childhood friends to help him run the growing brand. As of 2020, the MrBeast team was made up of 30 people.

As of November 28, 2021, Donaldson's main YouTube channel "MrBeast" has 81.1 million subscribers and 13.5 billion total views. It is the 7th most-subscribed channel on YouTube, as well as the second most subscribed channel owned by a YouTuber, and the most subscribed owned by a YouTuber from the United States. Aside from his main channel, Donaldson has seven other YouTube channels, including MrBeast Shorts and MrBeast Gaming, the latter reaching over 10 million subscribers in less than one year. Across his eight channels, Donaldson has 151.7 million combined subscribers, and 20.2 billion combined views across eight of these channels.

In 2019, Donaldson won the Breakout Creator by Streamy Awards. At the 12th Annual Shorty Awards in 2020, he won YouTuber of the Year. He was also one of the top 10 highest-paid YouTubers of 2020, alongside other personalities such as Markiplier, Ryan's World and Blippi.
