The radio network's primary operations and Public Information Files are located on George Rogers Boulevard in Columbia, near Williams-Brice Stadium.

The S.C. Educational Television Commission had its mission broadened to include FM radio in the late 1960s.

Until 2001, the stations were known as the South Carolina Educational Radio Network (SCERN), airing a mix of classical music, NPR news and locally produced programs.

The eighth station, WNSC-FM in Rock Hill, began airing exclusively jazz music in order to avoid programming duplication with WFAE and WDAV in Charlotte.

All stations simulcast NPR's Morning Edition and All Things Considered along with distinctive local programming.

All stations are fed programming directly from Columbia, although ETV/South Carolina Public Radio maintains several local offices.
