SAN FRANCISCO — Tango is joining the conga line of mobile messaging services that have turned into hot commodities as more people use them to communicate and share photos, music and other content. China's Alibaba Group is making the latest big bet on the trend with a $215 million investment in Tango and its 200 million registered users. Tango, a Mountain View, California, startup, has accumulated the audience in just four years since the debut of its mobile messaging service. Another group of investors that includes Yahoo co-founder Jerry Yang is anteing an additional $65 million to raise the total funding round to $280 million. Alibaba is buying into Tango's future just a month after online social networking leader Facebook Inc. announced plans to acquire mobile messaging service WhatsApp for $19 billion. That deal came together after another mobile messaging service, Snapchat, rejected a $3 billion takeover offer from Facebook. – AP
