Microsoft is teaming with YouTube, Twitter and Facebook to combat terrorism online. In a joint statement published on Twitter's public policy blog, the companies announced today that they will form the Global Internet Forum to Counter Terrorism in a move to collaborate on efforts to push back against content from terrorist and other extremist groups online.

Through the partnership, the companies say they will work to develop and share new technologies for detecting and eliminating terror-related content across their services. The effort also involves working reaching out to smaller tech companies to help them counter extremist content, while also formalizing best practices.

The spread of terrorism and violent extremism is a pressing global problem and a critical challenge for us all. We take these issues very seriously, and each of our companies have developed policies and removal practices that enable us to take a hard line against terrorist or violent extremist content on our hosted consumer services. We believe that by working together, sharing the best technological and operational elements of our individual efforts, we can have a greater impact on the threat of terrorist content online.

The initiative, Twitter explains, stems from and builds upon recent discussions and meetings with the UK government and European leaders. The companies say that the scope of its work "will evolved over time," but the hope seems to be that a concerted approach backed by private tech companies combined with efforts in the public sector will be effective in reducing the real-world impact of extremist content across the web.
