Bradley "The Rad Brad" Colburn is a sensation in the gaming world, for his detailed and humorous video game "walkthroughs" (when he explains how to play and beat a game). He is known for his profane and hilarious outbursts, sometimes even breaking chairs when he can't beat a level in a game. Colburn got his start through the popular gaming website Machinima, which specializes in creating animated videos using video games. Colburn began making the "walkthroughs" while finishing college and working a part-time job at Best Buy. When he graduated, he decided to give YouTubing full-time a try. In the past nine months, Colburn has jumped from 700K subscribers to 2.32M and counting.
