Kevin Ryan has checked the archives of the Washington Post and NYT if the instructions of this memo might have effected the reporting style of these newspapers. Here is what he found:

This cultural phenomenon goes back to 1967. At that time, in response to questions about the Warren Commission Report (which President Ford helped create), the CIA issued a memorandum calling for mainstream media sources to begin countering “conspiracy theorists.”[13]

In the 45 years before the CIA memo came out, the phrase “conspiracy theory” appeared in the Washington Post and New York Times only 50 times, or about once per year. In the 45 years after the CIA memo, the phrase appeared 2,630 times, or about once per week.

Before the CIA memo came out, the Washington Post and New York Times had never used the phrase “conspiracy theorist.” After the CIA memo came out, these two newspapers have used that phrase 1,118 times. Of course, in these uses the phrase is always delivered in a context in which “conspiracy theorists” were made to seem less intelligent and less rationale than people who uncritically accept official explanations for major events.

President George W. Bush and his colleagues often used the phrase conspiracy theory in attempts to deter questioning about their activities. When questioned by reporters about an emerging scandal in September 2000, Bush said the idea that his presidential campaign was flashing subliminal messages in advertisements was absurd, and he added that “conspiracy theories abound in America’s politics.”[14] When in 1994, Bush’s former company Harken Energy was linked to the fraudulent Bank of Credit and Commerce International (BCCI) through several investors, Bush’s spokeswoman, Karen Hughes, shut down the inquiry by telling the Associated Press — “We have no response to silly conspiracy theories.”
