Other media companies in general.
Less than 1% of public stocks in the US have that arrangement. It's extremely uncommon.
Among public companies with market caps above $5 billion, there are extraordinarily few stocks in which founders/families have almost all of the voting power. You can count them on one hand.
And, as it happens, so many people own equities passively (through a managed mutual fund, or an index fund, retirement account and the like) and ownership of a company is so diffuse, these provisions have little impact in practice except against another large entity.
I'm not defending the practice -- I think it is a bad management practice myself and don't buy stocks with such provisions -- I'm simply responding to your comment.
