It is located in Hilliard, a suburb of Columbus, Ohio.

It is the largest collection in the United States.

The Dave Johnson collection of early television cathode ray tubes is also at the museum, along with early TV studio equipment, which includes a working 60-line flying-spot scanner TV camera.

Visitors are pictured by this camera as they would have appeared on mechanical television in 1931.

The museum is a non-profit foundation operated by the Early Television Foundation, which hosts an annual conference at the museum.
