History of video games turn promoted the adoption of computers by universities, government organizations, and large corporations as the decade progressed. It was in this environment that the first video games were born. The computer games of the 1950s can generally be divided into three categories: training and instructional programs, research programs in fields such as artificial intelligence, and demonstration programs intended to impress or entertain the public. Because these games were largely developed on unique hardware in a time when porting between systems was difficult and were often dismantled or discarded after serving their limited purposes, they did not generally influence further developments
First video-recording from a submarine successful video-recording of the inspection of Tenneco’s "Molly Brown" 32,500 barrel oil storage unit. Fred Hartdegen, Gulf Coast Operations Manager for Hydro Products, and James Smith, Hydro Products Field Operator, reconfigured a Sony two-inch, helical-scan video-recorder to fit through the hatch of the sub (video-recorders in the 1960s were a relatively new technology and were rather large) and used a “frequency stabilizer” from Cubic Corporation for the power supply. The “frequency stabilizer” converted the sub’s DC power (which varied significantly during maneuvering) to a stable DC which was then electronically converted by crystal oscillators into an AC sine wave with
