GamerGate has made its way out of the internet trenches of 4chan and 8chan and into mainstream media, most recently with Stephen Colbert dedicating a portion of his show Wednesday night to the topic (including his obsession with Ms. Pac-Man) and interviewing host of "Feminist Frequency" Anita Sarkeesian.
For those out of the loop, here's a brief overview of GamerGate via Know Your Meme:
GamerGate refers to the online backlash against perceived breaches of journalistic integrity on video game news sites that occurred as a result of the Quinnspiracy, an online controversy surrounding indie game developer Zoe Quinn's alleged affairs with a number of men working in the video game industry, including Kotaku staff writer Nathan Grayson.The movement has also resulted in an online battle over sexism in video games, and threats of violence towards women.
