In 1992, the company relisted on The Stock Exchange of Hong Kong Limited, establishing a dual primary listing with London. In 1993, the company established its American depositary receipt programme. VTech delisted voluntarily from the London Stock Exchange on 7 October 2008. It also terminated its American Depositary Receipt programme with effect from 21 January 2011. History VTech was founded in Hong Kong in October 1976 by two local entrepreneurs, Allan Wong (Chi-Yun) and Stephen Leung. When the first single-chip microprocessor, the Intel 4004, became available in the early 1970s, the company saw the potential it offered for portable consumer electronics products. Wong & Leung set up a small factory in To Kwa Wan, with a investment and a staff of 40 people. In the first year, turnover was less than $1 million. VTech initially focused on developing video games. In 1977, the company created its first home TV game console, a version of Pong. Since only consumers in North America and Europe could afford such items, the company targeted primarily these markets. The United Kingdom was chosen as the first market for Pong, as Hong Kong and the UK used the same standard for television systems. In 1978, the founders introduced LED games they had developed to buyers from RadioShack in the US, which were sold under the RadioShack brand. 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
