Timeline image for 1930s The 1930s witnessed the explosive growth of radio and experimentation with a developing technology called television. Lehman Brothers underwrote the initial public offering for DuMont, the first television manufacturer, and helped fund the Radio Corporation of America, known as RCA.

Beginning in the 1930s, the increasing demand for oil set off waves of wildcat drilling in search of the resource. Companies like Halliburton and Kerr-McGee relied on Lehman Brothers for capital to fund their activities.
