10.The Big Brother in the novel 1984listens to everything and nothing can escape his ears.Now in reality,we have Facebook.The social media giant has never denied that it's keeping track of conversations you have near your phone ( if the Facebook app is open,that is ),but not,one expert has told NBC that Mark Zuckerberg's empire may be keeping ears on you at a more regular basis.According to Professor Kelli Burns,who teaches mass communication at the University of South Florida,it may be listening more often than it lets on.
To prove her point,Burns turned on the microphone feature on her phone,and said,"I'm really interested in going on an African journey.I think it'd be wonderful to ride in one of those jeeps."Less than a minute later,when she checked her Facebook page,she was met by a story about a journey-the first post on her newsfeed.There was also a car ad on her page.
While Facebook says that it's only keeping its ears open to help"identify the music you're listening to and TV matches you're watching,"Burns'little experiment suggests that there may be other motivations at play as well.But the social media company has denied claims that it records any conversations,and told The Independent,"Facebook does not use microphone audio to inform advertising or News Feed stories in any way.Businesses are able to serve related ads based on people's interests and other statistic information,but not through audio collection."
Whether you believe this statement or not,there are ways to stop Facebook from listening in at all.Simply turn off your phone's microphone by heading over into Settings ( if you're an iPhone user ),going to the Privacy tab,then clicking on Microphone.From there,you can remove Facebook's mic privileges,and probably,stop the company from hearing your conversations.On Android,you can also go to Privacy under the Settings tab,and change Facebook's permissions.
So the next time you're chatting with your friends about your summer vacation plans,keep an eye on your Facebook feed.There may be more participants in your conversation than you realize.
