On (formerly with Gwen Ifill) guest journalists weigh in on issues of the week in this venerable roundtable, the first program ever fed by PBS (previously it had aired on WETA-TV in Washington, D.C., and other East Coast public stations). Though its format is panel discussion, there have been occasional one-on-one interviews, a notable example being host Paul Duke's 1994 White House visit with President Bill Clinton. The series won a DuPont-Columbia University Award in 1974.
