Princeton, New Jersey is a community located in Mercer County, New Jersey, United States. Princeton University has been sited in the community since 1756. Although Princeton is a "college town", there are other important institutions in the area, including the Institute for Advanced Study, Educational Testing Service (ETS), Opinion Research Corporation, Siemens Corporate Research, Bristol-Myers Squibb, Sarnoff Corporation, FMC Corporation, The Robert Wood Johnson Foundation, Amrep, Church and Dwight, Berlitz International, and Dow Jones & Company. The community is roughly equidistant from New York and Philadelphia. Princeton has been home to New York commuters (via Princeton Junction) since the end of World War II. The community is close to many major highways that can take residents to both cities. While the Amtrak ride time is similar to each city, the commuter train ride to New York — via New Jersey Transit's Northeast Corridor Line — is generally much shorter than the equivalent train ride to Philadelphia, which involves a transfer to SEPTA trains in Trenton. Princeton receives some TV and radio broadcasts from both cities.
