The first DVR Blue prototypes were unveiled by Sony at the CEATEC exhibition in October 2000. The core technologies of the formats are similar. Sony commmenced two projects in collaboration with Panasonic, Philips, and TDK, applying the new diodes: UDO (Ultra Density Optical), and DVR Blue (together with Pioneer), a format of rewritable discs that would eventually become Blu-ray Disc (more specifically, BD-RE). Following protracted development, blue laser diodes operating at 405 nanometers became available on a production basis, allowing for development of a denser storage format that could hold higher-definition media, with prototype discs made with diodes at a slightly longer wavelength of 407 nanometers in October 1998. The information density of the DVD format was limited by the wavelength of the laser diodes used. Kees Schouhamer Immink received a personal Emmy award for his pioneering contributions to the DVD and the Blu-ray Disc.
