by Sears, in its catalogue, which was a popular shopping guide. Next VTech made the video game console CreatiVision. An electronic product with an external projector from French company Ludotronic was adapted by VTech and sold as the VTech ProScreen in 1984, following the release of VTech's Gamate and Variety handheld products the year prior. VTech then branched out into personal computers, including a series of 8-bit TRS-80 competition computers named the Laser 200, 210 and 310, as well as a series of IBM compatible PCs both beginning in 1983, followed by Apple II compatible computers, beginning in 1985, including a model called Laser 128. VTech exited the personal computer market in 1997 due to tight competition. In 1985, the United States Federal Communications Commission (FCC) allocated the frequency band 900MHz to ISM (industrial, scientific and medical) devices. Taking advantage of this, VTech began development on a cordless telephone, using the 900 MHz band, and in 1991 introduced the world's first fully digital 900 MHz cordless telephone. In 2000, to expand its cordless phone business, VTech acquired the consumer telephone business of Lucent Technologies. The acquisition also gave VTech the exclusive right for 10 years to use the AT&T brand in conjunction with the manufacture and sale of wireline telephones and accessories in the United States and Canada.
