A lot has changed since we gave the Panasonic TC-P50V10 our Editors' Choice award last year. The most relevant to the review you're reading now can be summed up with the eminently Google-able phrase "Panasonic black levels." The short story? Testing revealed that 2009 Panasonic plasmas lose their excellent black-level performance--the crucial ability to produce as dark a shade of black as possible--over less than a year of typical use. They become, literally, grayer, and lose the very edge that made them stand above the pack in the first place. As a result we lowered their picture quality scores across the board, and removed that Editors' Choice award.
