It's not really a new phenomenon is it?

> Cambridge Analytica, the British political consultancy caught up in a huge scandal over its use of Facebook data, has boasted that they ran the successful campaigns of President Uhuru Kenyatta in the 2013 and 2017 Kenyan elections. In a secretly filmed video, Mark Turnbull, a managing director for Cambridge Analytica and sister company SCL Elections, told a Channel 4 News’ undercover investigative reporting team that his firm secretly stage-managed Kenyatta’s hotly contested campaigns. [...]

> Cambridge Analytica boasts of manipulating voters’ deepest fears and worries. Last year’s Kenyan election was dogged by vicious online propaganda targeting opposition leader Raila Odinga, with images and films playing on people’s concerns about everything from terrorism to spiralling disease. No-one knows who produced the material. Cambridge Analytica denies involvement with these toxic videos – a claim that is hard to square with the company’s boast that they “staged the whole thing.”

> The IRD... played a major role in Western news and cultural media from 1948-1977. It financed a publishing house ‘Ampersand’ and at one time employed a staff of 300. A secret Foreign Office memo in February 1948 described the establishment of the IRD as a response to the “developing communist threat to the whole fabric of Western civilization”. The origins of the IRD lie in the recommendations in a paper put up by the Imperial Defence College.

> In their book on the IRD, Lashmar and Oliver note that “the vast IRD enterprise had one sole aim: To spread its ceaseless propaganda output (i.e. a mixture of outright lies and distorted facts) among top-ranking journalists who worked for major agencies, papers and magazines, including Reuters and the BBC, as well as every other available channel. It worked abroad to discredit communist parties in Western Europe which might gain a share of power by entirely democratic means, and at home to discredit the British Left”.

> IRD fed information and propaganda on 'communists' within the labour movement through confidential recipients of its briefings one of whom is now known to be the late Vic Feather into the media, and into the Labour Party's policing units, the National Agent's Department and the Organisation Subcommittee.

There've been paid liars and propagandists since people got the idea that voting was a thing. Probably before.
