Variety: CNBC experimented with the Meerkat broadcasting app — albeit briefly — apparently becoming the first big media brand to use the fledgling service. The biz-news channel used Meerkat to webcast Jim Cramer’s ringing of the opening bell at the New York Stock Exchange to celebrate “Mad Money’s” 10th anniversary. The Meerkat app lets users broadcast live-streams, with notifications to followers via Twitter. Viewers can only watch Meerkat video live, not on-demand.
