In the battle between Netflix and HBO, things are continuing to heat up. In its most recent quarter Netflix pulled way ahead of HBO in terms of its number of US subscribers, and saw shows like House of Cards pick up the kind of awards HBO is used to winning. But Netflix still trails far behind HBOs more than 100 million global subscribers and doesnt produce nearly the volume of original content. Today Netflix formally announced it was planning to raise $400 million in debt to fund European expansion and the creation of new original shows.
