Jaleco was founded as Japan Leisure Corporation on October 3 1974. In 1982, the company started developing and manufacturing arcade video games; as a result Japan Leisure Corporation shortened its name to Jaleco the same year. Jaleco was a video game company whose focus lay in arcade titles, as well as titles for the NES and other popular computer and video game consoles of the 1980s and 1990s, most notably the Bases Loaded series and Carrier. The U.S. arm of Jaleco was Jaleco USA based near Chicago in the town of Wheeling, Illinois.
By the year 2000, Jaleco, still active in the development of arcade and console video games, hadn't produced any hit title in years and was in a struggling state. Its American division Jaleco USA had already left the arcade industry in 1993. On November 1, 2000, Jaleco was acquired by Hong-Kong company PCCW. Jaleco, renamed PCCW Japan, gave the PCCW Group a foothold in Japan. PCCW heavily restructured the company, shutting down Jaleco's arcade division and other non-profitable departments in order to focus on video games for consoles of the sixth generation era. PCCW Japan itself acquired on April 2001 the VR-1 Group which included VR-1 Entertainment, a U.S. developer of massively multiplayer online role playing games, in order to bring a more global focus to its current and future software endeavors. On October 2002, PCCW Japan merged Jaleco USA and VR-1 Entertainment to form Jaleco Entertainment, its new U.S. division that would be based in Buffalo, New York instead of Wheeling, Illinois. PCCW Japan reverted its name back to Jaleco in 2004.
Jaleco is today a highly active publisher of video games for Microsoft's Xbox, PC games, and Sony's PlayStation 2. Jaleco is the official subsidiary of the whole PCCW Group in Japan which includes many activities unrelated to videogaming such as music, web application and mobile phone content.
On May 31 2006, Jaleco's board of directors opted for a change of name from Jaleco Ltd to Jaleco Holding Ltd and, in the process, spun off the video game division into a separate company that would take the name of Jaleco Ltd. As such, Jaleco Holding is now the name of the company that has existed since 1974, while Jaleco Ltd is the new company that was established on July 3 2006 as a wholly owned subsidiary of Jaleco Holding.
