The quarterly figures, released by games analyst Daniel Morse, show Nintendo sold 51,744 Wiis, whereas Microsoft sold 45,036 Xbox 360s.

We then checked with Leslie Chard, president of HDMI Licensing, which owns the rights to the standard, who told us that HDCP is one component of HDMI that has been plagued with interoperability issues. HDCP (high-bandwidth digital content protection) is designed to prevent the interception of data — specifically copyrighted Hollywood movies — between an output component and a display. As Steve Balough, the president of Digital Content Protection, the licensing company for HDCP explains, the two pieces of hardware must exchange a "key," a sort of certificate of authenticity unique to each individual device, to verify a secure connection.
