As time progressed, Nelsonic experimented with higher-end products such as metal watches and increasingly complex game-watch designs. In 1990 the watch-making giant, M.Z. Berger, made a large bid and was able to successfully purchase the company.[20] For a period of nearly a decade after this acquisition, M.Z. Berger continued to use Nelsonic as a subsidiary branch and to employ the Nelsonic mark in the release of game-watches and the production of new re-releases of popular models from the 1980s and early 1990s.[nb 2] By the end of the 1990s, however, public interest had waned (quite possibly due to the rise in popularity of more advanced handheld video game consoles and, eventually, of other portable computing devices, such as PDAs and smartphones) and this practice came to an end as M.Z. Berger shifted markets to target higher end consumers more exclusively.
