To make MapQuest a serious contender in the online spatial application market, a robust set of geographical tools was developed under Greenman's direction. The initial Denver team consisted of Evans, Simon Greenman, Chris Fanjoy and Harry Grout. Sensing the emerging demand for spatial applications on the Internet, and with crippling network latency in Lancaster, the executive team of Barry Glick and Perry Evans moved MapQuest to the up-and-coming LoDo area of Denver, Colorado. MapQuest's original services were mapping (referred to as "Interactive Atlas") and driving directions (called "TripQuest"). Much of the code was adapted for use on the Internet to create the MapQuest web service in 1996. In 1994 it was spun off as GeoSystems Global Corporation.

Donnelley & Sons began generating maps and routes for customers, with cooperation by Barry Glick, a University at Buffalo Ph.D. Donnelley & Sons in Chicago, which moved to Lancaster, Pennsylvania, in 1969. MapQuest's origins date to 1967 with the founding of Cartographic Services, a division of R.R. The former MapQuest logo was phased out as part of a website redesign unveiled on July 14, 2010.
