Spring of 2015 now goes down in tech history as the advent of “lifestreaming,” or livestreaming daily activity through mobile devices. Meerkat launched in February, and as the official app of SXSW Interactive, quickly became the new social magnet, attracting brands, digital strategists, and early adopters alike. A few weeks later, in March, new-to-market Periscope was dominating downloads. The one-year-old startup which was purchased in January by Twitter in an effort to fight its decline in user acquisition, became the biggest competitor to Meerkat overnight.
