The line between Twitter and its livestreaming service, Periscope, is beginning to fade. Starting today, anyone can broadcast by hitting the compose tweet button inside Twitter's iOS and Android apps, followed by the "Live" button. Instead of being bounced to the Periscope app, however, you'll now start start a livestream immediately. The functionality is still "powered by Periscope," and indeed the experience is mostly the same as before -- you write a quick caption before you go live, and then registered users can leave hearts and comments while you stream. Is this a direct reaction to Facebook Live's growing popularity? Almost certainly.
