Facebook Live has taken away the last reason to watch TV
Facebook and Twitter are making a play for live sporting events as well

Last Wednesday, police in Falcon Heights, Minnesota, shot and killed a man named Philando Castile during a traffic stop. His girlfriend, Diamond Reynolds, was riding in the car at the time.
She opened the Facebook app on her phone and broadcast the aftermath of the shooting using the new Facebook Live feature. Anybody who tuned in was able to watch the graphic image of Castile bleeding.
The next day, protests against police violence erupted around the country.
During one of those protests, in Dallas, a gunman shot a dozen police officers. So far, five have died.
This time, a Facebook user named Michael Kevin Bautista broadcast the action live.
As of Friday afternoon, each video had been watched more than 5.4 million times.
