XBR: Designation for Sony’s high-end, top-quality television offerings. For a brief time the XBR line was not the top Sony television offering, that honor going to the short-lived Sony Qualia line. See Qualia.
XBR2: XBR Squared, referring to the Sony KV-32XBR100, a 32 inch tube NTSC TV widely regarded as the best television of its type ever produced. The KV-32XBR100 carried its tuner and input connections in an external box had a tube that was almost perfectly flat in the front. It was introduced in 1994 and sold for over $3,000 at the time (remarkable considering the same sum gets you a very large HDTV in 2007.)
xD Picture Card: Compact memory card format used primarily in Fujifilm and Olympus digital cameras.
XLR Connections: See Balanced Connections.
XM Satellite Radio: Subscription satellite radio service sold throughout North America with over 170 stations. See Sirius Satellite Radio.
