Operation Mockingbird is an alleged large-scale program of the United States Central Intelligence Agency (CIA) that began in the early years of the Cold War and attempted to manipulate news media for propaganda purposes. It funded student and cultural organizations and magazines as front organizations.
According to author Deborah Davis, Operation Mockingbird recruited leading American journalists into a propaganda network and influenced the operations of front groups. CIA support of front groups was exposed when a 1967 Ramparts magazine article reported that the National Student Association received funding from the CIA. In 1975, Church Committee Congressional investigations revealed Agency connections with journalists and civic groups. None of the reports, however, mentions by name an Operation Mockingbird coordinating or supporting these activities.
After the Watergate scandal in 1972–1974, the U.S. Congress became concerned over possible presidential abuse of the CIA. This concern reached its height when reporter Seymour Hersh published an exposé of CIA domestic surveillance in 1975. Congress authorized a series of Congressional investigations into Agency activities from 1975 to 1976. A wide range of CIA operations were examined in these investigations, including CIA ties with journalists and numerous private voluntary organizations.
The most extensive discussion of CIA relations with news media from these investigations is in the Church Committee's final report, published in April 1976. The report covered CIA ties with both foreign and domestic news media.
For foreign news media, the report concluded that:
The CIA currently maintains a network of several hundred foreign individuals around the world who provide intelligence for the CIA and at times attempt to influence opinion through the use of covert propaganda. These individuals provide the CIA with direct access to a large number of newspapers and periodicals, scores of press services and news agencies, radio and television stations, commercial book publishers, and other foreign media outlets. 
Mainstream Job is Disinformation
The job of mainstream media is not to inform, but to misinform the public, making it harder for people to make informed decisions about things that impact their own lives, and that of their families. Mass media is used to divert public attention from important issues and changes that are decided upon by the political and economic elites, through the technique of derailing important facts or information through the continuous flood of distractions, mindless entertainment and insignificant information. The controlled media and press have mandates to provide all news and related media content to be written or presented at no greater level than what a 12 year old child (or less) could understand. If all we have access to in the mainstream news and entertainment is being produced at a child’s level, what kind of impact does that have on significantly lowering literacy levels and human intelligence?
