Interesting to see how many people think that companies who are trawling your Facebook, Twitter, Google/YouTube accounts have no access to personal data and are only interested in directing a few targeted ads at you.
It goes way beyond simple adverts though. They are using AI's to scan every word you type, your social connections and every clue you give about your values and opinions to construct sophisticated psychological and socioeconomic profiles of you and using that to sell you goods but more importantly, to influence your social and political opinions.

The next biggie after social media is smart devises with all the big media giants currently filing patents that will allow your TV, your smart speaker and every other device with a network enabled camera, microphone or GPS to continually monitor everything you say or do.
