Allow me to add some information here, as the commentor hasn't asked for anything specific.

The United States disbanded USIA (the agency in charge of US propaganda) after the end of the Cold War in 1999. USIA was split into a couple components. Overt programs were given to the Department of State, covert ('black') programs to the Department of Defense and the Board of Broadcasting Governors were split off into their own organized body.

During the Bush administration there was a lot of turmoil about how to organize efforts - they found that splitting the efforts caused confusion as various programs weren't coordinated with the same messages. Bush created Policy Coordinating Committees for "Strategic Communication" to help interdepartment and interagency cooperation. Mostly during this time efforts were focused on the Middle East, and indeed today the US heavily blankets the Middle East with propaganda.

Things have evolved since Bush. There has been a growing role of social media analysis and interaction. The Department of State has a Digital Outreach Team where they will engage on forums in the Middle East (it's an overt program, so they will identify themselves) - but the goals as can be seen from FOIA requests and strategic documents are to confuse adversaries, 'get in their heads' and to engage parties whose opinion may be swayed. Covert operations do much of the same, but under false flags and with persona management software (check out Earnest Voice). You can find out more about these efforts by searching for the Department of States "war of ideas" or congresses "Jihad 2.0", or generally doing due diligence and reading legislation and strategy documents.

Another big change in US strategy is that its audience is much wider. Strategy documents toward the end of the Bush Administration and through the Obama Administration focus on the need to counter anti-American ideas abroad.

Now the CIA especially runs NGO and CSO fronts, many times through USAID, and more generally NGOs and CSOs are invested in if they align with US strategic objectives. If you like you can find CIA reports on investment in NGOs inside of Ukraine as part of their long term plan as project UNITER and how this turned out with NGOs leading Euromaiden protests (if you read foreign media - Germany's Der Speigel is a good source you may trust). ZunZuneo is a very transparent example because there's been lots of journalism on it - in this case the CIA set up a fake Twitter network in Cuba where they were monitoring citizens and planning to turn their network (peaking somewhere around 60,000 users) into an outlet to stir dissent and organize protests.

Many countries try to quell this activity. Cuba, for example, banned smart phones at one point. Russia recently, after the Ukraine affair, kicked out all NGOs with funding from or ties to Western governments.

Aaannnyyway. There's tons of more details to be had (US research into manipulating social networks a la DARPA SMISC, Project MINERVA) but in reading through material and reports on the various task forces of Congressional meetings it's quite clear - though really not surprising as these have been longstanding US practices.

If you would like to read more about propaganda and CIA fronts in the Iraq war, searching for Rendon Group, the Iraqi National Council, and the Office of Strategic Influence.

The United States unequivocally funds and supports NGOs and CSOs that align with its strategic interests and invests them as operating fronts for special operations. This isn't really something that's widely contested.

The Department of Defense (just search for this using your favorite client/search engine) is right now investing large amounts of money through partnerships with Venture Capitalists into Silicon Valley and the tech sector. There is a call for both cybersecurity startups and for civil society apps.

Google is offering (and there are plenty of examples of Google's involvement with US national security investments, perhaps you'd like to ask about this) to protect news and human rights agencies. This will of course be providing protection to US and US-aligned news media organizations and NGOs (they can call my bluff by supporting Chinese NGOs - and China is now starting to try to have its own culture export, news organizations, and human rights groups in Africa, South America and Eurasia).
