> Dual-class voting shares were illegal for most of the 20th Century, but came back in 1986. According to http://www.investopedia.com/articles/fundamental/04/092204.asp#axzz1rxM5WWdB http://www.investopedia.com/articles/fundamental/04/092204.a... , Ford has dual-class and I'm pretty sure that it has had it long before 1986. Of course, Ford may have had dual-class before the "most of the 20th century" rules were written and may have been grandfathered. FWIW, Berkshire-Hathaway (buffet's toy) has dual-class stock.
