Facebook, Twitter, YouTube and Microsoft have formed a new group to combat terrorism and violent extremist content on their platforms.
The Global Internet Forum to Counter Terrorism further cements the companies' counter-terrorism collaborations and aims to work with others in the effort.
"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," reads a shared blog post announcing the group.
Building on work by the EU Internet Forum and Shared Industry Hash Database as well as talks with the UK government and initiatives stemming from this year's G7 and European Council meetings, the Forum solidifies collaboration between its members and will explore areas where they can work together.
The group will also partner with smaller tech companies to develop technologies and procedures to combat terrorism, as well as work with civil society groups, academics, governments and international bodies such as the European Union and United Nations.
While the Global Forum to Combat Terrorism is new, these four companies have in the past partnered to combat terrorism online.
