Snap is going public: its filing shows widening losses and slowing user growth, calling into question its ability to reach profitability and justify the ~$20 billion valuation it is seeking

Netflix celebrated the 10-year anniversary of its streaming service by posting its largest quarterly rate of subscriber growth, adding just over 7m new subscribers in Q4 2016, smashing its own forecast for the period of 5.2m

5.12m of the new subscribers were for its international services, attributed to acceptance of its growing suite of English language original programs.
