In an effort to boost ridership, the Metropolitan Transportation Authority, North America's largest public transportation network, formed a committee under the leadership of John Tauranac in the mid-1970s to create a new, more appealing map for the New York City subway system and replace the iconic, Massimo Vignelli-designed — yet impractical and not universally loved — map in service at the time.

Michael Hertz Associates provided a new design, featuring more geographically correct lines, which was ultimately published in June 1979 in time for the subway's 75-year anniversary. It has remained the basis for all subsequent maps issued until today.

"The map that Mr. Hertz’s firm came up with included streets, neighborhoods and other surface reference points," writes Neil Genzlinger for the NYT. "And it depicted the city and its signature elements like Central Park and the waterways in a fashion more reflective of reality — the park wasn’t square, as on the earlier map, and the water wasn’t beige."
