Davidson & Associates (or simply Davidson) was an educational software company headquartered in Torrance, California and published the Blaster series, including Math Blaster and Reading Blaster. In 1995, Davidson released 3D Jungle Train for Windows 95 based on new 3D software in which the player had to find a lost diamond and would be rewarded with a video adventure to other parts of the jungle. Bob and Jan Davidson sold the company in the early 1990s and founded the Davidson Institute for Talent Development.
