[1][4] He is the Founder and President Emeritus of Internews, a global non-profit organization supporting independent media and access to quality information worldwide.

He wrote the book Citizens Rising: Independent Journalism and the Spread of Democracy (2013) to tell the stories of the media development field and the activists who are playing a decisive role in political affairs across the globe.

[1] Hoffman was the founder and co-director of Survival Summer, a coalition of 140 national peace and disarmament groups that helped launch the anti-nuclear war movement of 1980.

Building on the groundbreaking US-Soviet spacebridges[6] developed by Kim Spencer and Evelyn Messinger, Hoffman organized a series of seven satellite television exchanges between leaders of the US Congress and their counterparts on the Supreme Soviet.

Hoffman would go on to chair the board of Internews Europe after it moved its headquarters to London from 2014-2018, eventually handing over the role to the prominent British media lawyer Mark Stephens (solicitor).

Questions and comments were taped and shown to the judges and prosecutors at the court in Arusha and their responses were relayed back in further town hall events, creating a rudimentary, but effective, feedback loop.

Link TV is a non-commercial direct-to-home satellite television channel that provides a unique perspective on international news, current events, and diverse cultures, presenting issues not often covered in the US media.

[10] Hoffman and Jane Safly Rogers collaborated to launch the Earth Journalism Network (EJN)[11] to empower and enable journalists from developing countries to cover the environment more effectively.

Under the leadership of its Executive Director James Fahn, EJN has trained thousands of journalists to cover many environmental concerns including climate change, biodiversity, water, environment health, and oceans and coastal resources.

Specially trained journalists worked with surviving local media to provide life saving information during relief efforts in Aceh and Sri Lanka after the 2004 Indian Ocean tsunami, Haiti following the January 2010 earthquake, the Philippines in 2013 following Typhoon Haiyan among other humanitarian crisis.
