The Early Television Foundation Museum has opened in Hilliard Ohio, the only museum in the USA of this type.
It is a museum dealing not in the TV programming of the early era but the actual TV sets of the time 1928-1960.
The collection includes about 100 TV sets including 28 out of the 100 existing pre WWII TV sets thought existing. This a small museum but an interesting one.
