Zenith, Westinghouse, Philco, and General Electric are the same way. I believe that Westinghouse, General Electric, and RCA are all made by the same company and it is not an American company.
Audio products and A/V accessories under the RCA brand are part of Audiovox Corporation, which
is an American company. I'm not sure who owns the actual plants in Asia that build the products.

The RCA brand was broken up by Thomson Consumer Electronics, a French company that purchased RCA (and GE consumer products) from GE.
RCA Records now belongs to Sony. Large RCA TV's are sold and manufactured by ON Corporation. RCA portable TV's are sold by Innovative DTV Solutions, which is the same company that produced some Auvio digital and HD portable TV's for Radio Shack, and as mygoTV which is their own brand.
I would however put RCA on the bottom of the list when it comes to quality.
I wouldn't. Although they make some cheap products, Audiovox/RCA also produces the RCA Superadio III, considered to be one of the best high performance radios available today. The Superadio has great AM reception and the ability to make AM sound nearly as good as FM.
