Quite a discussion at the Craig Murray blog anent Cambridge Analytica and its parent company SCL. SCL is the acronym for Strategic Communications Laboratories based in the UK. Cambridge Analytica is the flea on the SCL elephant. SCL is a global firm with a star studded Board of Directors which has included even British royalty, high ranking military, intell, and the like. It is a Big Data firm specializing in information warfare, data mining and the like.
Here is a post from Craig Murray's blog listing known board members as of 2005:
"re: SCL Forgive me if I am repeating what has already been posted. If a search is conducted on ‘Strategic Communications Laboratories’ instead of ‘SCL’, different results come up – so despite ‘Strategic Communications Laboratories’ being one and the same as SCL, different results do seem to emerge depending on the explicit search criteria used (on google chrome):-
This link suggests that SCL goes back to at least 1993.
What is also interesting is that a whole host of names are listed on the above link, like so:-
