Netflix is no longer an up and comer, it's a giant, pushing out well-regarded original content -- in 4K even -- and constantly expanding its reach. Today we learned that HBO will finally hop off its cable-only throne and do battle with some sort of internet-only service next year, and as Netflix reveals how it did in the last three months, we'll find out how it plans to respond. According to CEO Reed Hastings' Q3 letter to investors, despite the "inevitable" move, he believes "it is likely we both prosper as consumers move to Internet TV." Meanwhile, his company has grown to 53 million customers worldwide and figures it will crack 57 million by the end of the year. The bad news? Those price hikes for new customers appear to have slowed growth, with Netflix adding 980,000 customers in the US, lower than both the 1.29 million net additions in the same period a year ago -- when it passed HBO in paid subscribers -- and the 1.33 million the company predicted just three months ago. There should be plenty to talk about when Netflix has its investor call at 6PM ET (live video streaming -- watch it embedded after the break).
