Facebook (FB) roundup: 1) Calcalist reports Facebook's buyout talks with Waze have stalled over Waze's insistence on maintaining its Israeli R&D center and keeping all its employees in the country (translation). 2) Another executive departure: Larry Yu, Facebook's PR chief for the last 5 years, is leaving to join a startup. 3) It's not exactly House of Cards, but Facebook is ramping its investment in its Facebook Live original programming series; Live typically features celebrity interviews and instructional videos. 4) BGR reports AT&T is planning to discontinue the HTC First (the closest we've gotten to a Facebook phone) less than a month after its launch. The First's ho-hum specs could be a factor, but chances are Facebook Home's underwhelming debut is as well.
