In 1972, Philips launched the world's first home video cassette recorder, in the UK, the N1500. Its relatively bulky video cassettes could record 30 minutes or 45 minutes. Later one-hour tapes were also offered. As competition came from Sony's Betamax and the VHS group of manufacturers, Philips introduced the N1700 system which allowed double-length recording. For the first time, a 2-hour movie could fit onto one video cassette. In 1977, the company unveiled a special promotional film for this system in the UK, featuring comedian Denis Norden. The concept was quickly copied by the Japanese makers, whose tapes were significantly cheaper. Philips made one last attempt at a new standard for video recorders with the Video 2000 system, with tapes that could be used on both sides and had 8 hours of total recording time. As Philips only sold its systems on the PAL standard and in Europe, and the Japanese makers sold globally, the scale advantages of the Japanese proved insurmountable and Philips withdrew the V2000 system and joined the VHS Coalition.
