Tenneco

In the 1950s, the company acquired existing oil companies, including Sterling Oil, Del-Key Petroleum, and Bay Petroleum. The Tennessee division of the Chicago Corporation acquired Tennessee Gas Transmission Company in 1943 to build a natural-gas pipeline 1,265 miles (2,036 km) from Texas to West Virginia. The first line was completed in October 1944. It was followed by three additional pipelines totaling 3,840 miles (6,180 km) during the next 15 years which provide gas to New York and New Jersey.

In February 2019, it was announced that Tenneco will be separated into two different companies, leading to the launch of DRiV Incorporated- a publicly traded Aftermarket and Ride Performance company that will serve as a global multi-line and multi-brand aftermarket supplier of ride performance and braking suppliers to light vehicle and commercial vehicle customers.
