The rural nature of the Great Valley section of the township started to disappear after 1950. The population of the township doubled in the 1950s, probably associated with the opening of the General Electric facility in King of Prussia, the Burroughs Research Laboratory in Paoli, the extension of the Pennsylvania Turnpike so that its eastern terminus was at Valley Forge, and the building of the Schuylkill Expressway. Later decades saw further housing developments culminating in the contentious building of Chesterbrook. Office developments accompanied the housing, with a concentration of financial firms, the biggest being Vanguard. Tredyffrin is now the most populous township in Chester County.
