Earlier quoted context omitted.
Check out Comcast which has two independent stocks (CMCSA, CMCSK). They move together pretty much, off by less than a dollar right now.
Is the difference between CMCSA/CMCSK similar to the GOOG/GOOGL difference (specifically, limited voting rights) or is it a different case?
CMCSA has voting rights, CMCSK does not.
(And there are also Class B shares which are not publicly traded, and have a guaranteed 1/3rd vote share. They are all under the effective control of the current President/CEO, who is the son of the original founder.)
