Johnson signed into law the Public Broadcasting Act of 1967, establishing the Corporation for Public Broadcasting (CPB) and, eventually, the Public Broadcasting Service (PBS), and National Public Radio (NPR).ÊThe Corporation for Public Broadcasting is the steward of federal funding that supports nearly 1,500 locally owned public radio and television stations. © 2017 Sesame Workshop LBJ Library photo by Jay Godwin
