The International Particle Physics Outreach Group (IPPOG) has recently (on 19 December 2016) been made into a formal collaboration.
Established 20 years ago, IPPOG has evolved from a European to a global network of members, which can include countries, laboratories and research collaborations, all with the aim of making a concerted effort to popularize particle physics.
The new collaboration status demonstrates a clear commitment towards sustainable and systematic science outreach. Already IPPOG has 13 official members who signed the memorandum of understanding, and contribute a membership fee, with more expected to join soon.
