AFP,SAN FRANCISCO:  Facebook on Wednesday ramped up its challenge to Twitter-owned Periscope with upgrades to the social network’s live video broadcasting feature. People using the Live streaming feature at Facebook will be able to “broadcast: to groups at the social network or in scheduled “events.” Scheduled events can even be used for online question-and-answer sessions. “We hope this new ability to both broadcast and watch live video within Groups and Events enables people to connect more deeply with their closest friends, family and the communities of people who share their interests,” Facebook product management director Fidji Simo said in a blog post. Facebook also began letting people replay comments made during live broadcasts or weigh in with reactions such as sad, angry, love, or ‘wow,’ that were launched recently in News Feed. “Live Reactions appear in real time and disappear quickly so broadcasters and other viewers can get a sense of how people are feeling at different points during the live video - it’s like hearing the crowd applaud and cheer,” Simo said. Data gathered by Facebook showed that people comment 10 times more often on live videos than on regular videos.
