Erik Range (born on 10 April 1977,  in Brunswick, Germany), also known by the alias Gronkh, is known for creating and publishing playthroughs of video games, known as Let's Plays. He publishes these playthrough videos on YouTube and markets them through the company PlayMassive GmbH (a website about computer games). Gronkh is one of the most popular representatives of the Let's Play genre in Germany.
Erik Range first gained fame in the gaming industry as a guide for Bard characters of the online role playing game Meridian 59. This is where he first appeared under the pseudonym "Gronkh" -- the alias he still uses today. Range himself explained the origin of his pseudonym, jokingly referring to it as a portmanteau of the name "Gregor Onkh". He has been managing partner and co-founder of Play Massive GmbH  since 2009 . Colleague, shareholder, manager, and fellow co-founder of the company is Matthias Valentin Rahmel, from Dormagen. Rahmel operates online under the pseudonym Sarazar, and collaborates with Range on YouTube. Since 2010, Range has regularly published Let's-Play videos in which he shows and comments on his progress in various games. He published his first video on April 1, 2010. It was initially dubbed a test recording for the online game Allods Online on his YouTube channel. Since then, he has become one of the most popular German-speaking providers of these formats. In addition, his YouTube channel has gathered over 2.6 million subscribers and over 960 million video views and holds claim as one of the most successful channels on the website. He is one of the first commercial German creators and providers of such videos. His work is supported by game manufacturers who hope to create promotions for their products through cooperation. The game developers of Daedalic recently reported an increase in sales of Edna bricht aus after Range discussed the game on his channel. Since early 2012, Gronkh has been registered as a trademark to PlayMassive GmbH, the German Patent and Trademark Office. Range is currently living in Cologne.
Range operates the website Gronkh.de as a part of the PlayMassive-Network. Featured on Gronkh.de are many of his various YouTube videos and a list of other Let's Play users of PlayMassive. Gronkh.de is financed purely through advertising sponsorship.
Range operates a real-life channel called Die Superhomies in cooperation with Rahmel, focused around the two men's travels. A special theme of the channel is Let's eat, where Gronkh and Sarazar (Rahmel) eat food from other countries. The channel has gathered around 200,000 subscribers since 2013.
His best known series is his Let's Play Minecraft series, which he started 19 October 2010. He publishes 10- to 20-minute episodes and generally collects around 150,000 views per video. There are over 1,000 parts of this series. Since May 18, 2012, the online video portal MyVideo usually features a live stream in which Sarazar and Gronkh play new games together or interact with the online community. The live stream regularly reaches over 65,000 spectators. On March 1, 2013, Range worked together with other representatives of Let's Play. They organized MyVideo live streams featuring Last Man Standing videos, in which he played various computer games with his team against PietSmiet's hard reset for about 8 hours. The live stream has more than 1 million viewers. Since mid-April, in addition to the live stream, a 24-hour stream of the Let's Plays video and other commentators of GronkhDE are shown.
