 As GEIS, the service was expanded with Fortran 77 and C programming languages (1985), but was hard hit by the availability of Personal Computers supplanting much of the isolated computational loads previously accomplished on time sharing.GEIS refocused on "Network-Based Services" where the world-wide availability of homogenous access to a customer's applications and data could be leveraged to advantage.Services like sales-force reporting, international banking and transfers, customer support and eventually e-mail (delayed by GE's aversion to running afoul of international common-carrier laws) all required a highly reliable worldwide network and GEIS had the biggest and the best.
