Ganache is chocolate and cream. White chocolate ganache will be made by melting white chocolate and then adding cream. This is likely to be a lot sweeter than average ganache (dark chocolate) as white chocolate is sweeter in general and contains less cocoa solids.
Hershy's made the first white chocolate. It was invented by a German scientist named Herman Golvinsky. He showed his work to hershy's and they produced or "made" it.
Brown chocolate is made from cocoa. White chocolate really isn't chocolate at all because it is made from sugar, but since there are no regulations in place to say what has to go into chocolate for it to have the name it is still called chocolate.
