Biography
After dropping out of the University of Cincinnati, Mark started on YouTube in September 2011 with his first channel, which had very few views and subscribers. In May 2012, after some issues with monetization, Mark jumped ship to his second and current channel, MarkiplierGAME, now called simply Markiplier. The channel has since gained over 23 million subscribers and 10 billion total views, accumulated over time from collaborations and playing popular horror and indie games. Mark has also done dozens of vlogging and sketch comedy videos, and has raised over $1,000,000 for a variety of charities.

For some time, Mark worked closely with sketch comedy team Cyndago until one of its members, Daniel Kyre, attempted suicide in September 2015 and died soon afterwards in hospital. Mark took a brief hiatus from YouTube after Daniel's death, returning to YouTube full-time in late 2015. In the same year, he also adopted a golden retriever named Chica.

In late 2016, Mark formed a team of friends to assist in creating higher-quality videos, consisting of his friends Ethan Nestor, Kathryn Knutsen and Tyler Scheid, and his girlfriend Amy Nelson. As of 2018, Kathryn is no longer working with Mark full-time.
