use the well known Osram and Sylvania brand names in their corresponding and representative markets throughout the world. Advertising From 1951 until 1956, Sylvania sponsored the game show Beat the Clock. The grand prizes on the show would be Sylvania television sets, and some consolation prizes would be Sylvania radios. Sylvania "Blue Dot (tm) for sure shot" flashbulbs would be used to take a photograph of the contestants in awkward outfits or messy stunts. One of Sylvania's heavily advertised TV features was a lighted perimeter mask of adjustable brightness called "HALOLIGHT", which was purported to ease the optical transition if a viewer glanced from a dark background to the bright TV screen. Today Philips markets an Ambilight feature, lighting the wall behind a flat display to soften the viewing experience. HALOLIGHT could not be adapted for color TV, because color TV white balance (aka tracking from low to high brightness) was unpredictable. Since the white color temperature of the HALOLIGHT and the illuminated color screen could not be made equivalent, HALOLIGHT was withdrawn. Osram Sylvania sponsored the It's a Small World ride at Disneyland in California with a twelve-year agreement starting in 2009. In 2014, the sponsor logo at the attraction's entrance changed to that of Siemens, the parent company of Sylvania. Accidents The Sylvania Electric Products explosion, which involved scrap thorium, occurred on July 2, 1956, at their facility in Bayside, Queens, New York City. The incident injured nine people; one employee subsequently died of his injuries.
