VTech then began to build its own brand. Starting in the early 1980s, a line of electronic games would be manufactured. VTech unveiled its first electronic learning product, called "Lesson One", at the New York Toy Fair, in February 1980. It taught children basic spelling and maths. An exclusive version under the name "Computron" was offered to Sears, with the product being prominently advertised 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.
