Sony is angling for a big slice of the home theater market with its new product lineup. At a late February retailers' showcase held in New York, the manufacturing giant trotted out no fewer than 12 new integrated HDTV sets and two new high-definition digital video recorders.

The WB Television Network and Chicago-based Tribune Broadcasting announced Wednesday, August 21 that they would provide five hours per week of original high definition digital programming beginning this fall. The 1080i broadcasts will begin September 12, according to a joint announcement by Jed Petrick, WB Network president, and Pat Mullen, Tribune Television president.

Poly-OLED. Add this new acronym to your technophile lexicon.
