If you haven’t already heard of Periscope then prepare to soon. Periscope is Twitter’s live streaming app which the online social networking site acquired earlier this year and recently launched to consumers. Within the first 10 days following its launch 1 million users had signed up which is pretty good going. Early brand adopters include Starbucks and Spotify who have already posted Periscope streams. We think it’s a great new marketing tool for brands. Q & A’s, Behind the scenes and Meet the Team footage will all help build a brand’s personality and transparency. Of course, like all social media, it will have to be carefully monitored but we think it’s worth a punt, like millions of others.
