This might seem a small detail, but I find it fascinating that Comcast customers do not have to go through Netflix to be able to buy access to the excellent House of Cards series that Netflix brought to life.

The cable giant struck a pact with Sony Pictures Home Entertainment, giving Comcast rights to sell the Emmy-winning first season of “House of Cards” through the recently launched Xfinity Store service. Netflix currently owns exclusive streaming rights to the Media Rights Capital-produced series, while Sony handles international and homevideo distribution.

This is getting complicated. The lines that distinguish streaming and home video are getting blurred. Interesting stuff.
