It is just a name. Radio Corporation of America was bought lock stock and barrel by General Electric back in the 80s. GE kept NBC and the Defense Contractor business ( think Aegis Missile System) and then sold off everything else.
A French outfit ended up with GE's consumer electronics business which included GE and RCA TV and related products.
Brand names often live on long long after the companies that owned them have ceased to exist.
Very true; brand names are often the most valuable asset a company has. That's why GM still markets Pontiac, Chevrolet and Buick decades after buying them out.
