Daniel Middleton (born 8 November 1991) is a British YouTube personality and professional gamer who goes by the handle The Diamond Minecart or DanTDM. His online video channel mainly focuses on the popular game, Minecraft. As of March 2016, he has over 11 million subscribers, and is listed among the top YouTube channels in the United Kingdom. In 2014, Business Insider estimated Middleton's annual income to be somewhere between $213,000 and $2.15 million. In July 2015, his channel was listed as one of the most popular YouTubers in the world by viewership.
Middleton was born on 8 November 1991 in Aldershot, England. He is the eldest of two siblings. His parents divorced when he was a child. He attended Northampton University and started a YouTube channel dedicated to Pokémon while at university, in which he called himself "PokemanDanLv45".
In 2012, Middleton created The Diamond Minecart, a more professional, children-focused gaming channel. His YouTube channel name eventually changed to TheDiamondMinecart // DanTDM. He produces videos out of his home studio in Wellingborough. In an interview with The Big Issue, Middleton describes his process in making videos: he gets up around 9am and starts working on the video an hour later. He checks for Minecraft updates, edits the videos in the afternoon, and uploads the finished product at 8:30pm, after which, he checks for comments. He said "There isn’t another game where free content comes out every day made by fans, and some of it is mind blowing." On weekends, he prepares videos in advance. In addition to Let's Play-styled videos, he makes mini films that involve original characters. He also started a vlogging channel named MoreTDM, in which he posts videos about his daily "non-Minecraft" life.
Middleton has been a regular guest at the Insomnia gaming festival, where he appeared on the big stages in editions 49, 52 and 53. He was also featured twice on BBC's Technobabble - where he commented on several videogames, and once on ITV's Lorraine - where Middleton talked about being a YouTuber.
