In today's #privacy (or lack thereof) news:

"A new report from 404 Media that cites documents leaked to its reporters reveals "Active Listening" #software that, unsurprisingly, uses a form of artificial intelligence to "capture real-time intent data by listening to our conversations". The leaked documents cite a pitch deck from Cox Media Group (CMG), a TV and radio giant that is one of Facebook's alleged marketing partners."

I think we've all known this has been happening. It was way too common for me to talk to someone about something and then start seeing targeted advertising knowing I never did any sort of cursory web searching on the topic.
