Shari is still on the boards of Viacom and CBS (she's vice-chairman), but it's clear that Daddy Dearest has no great desire to have her take over his role as chairman upon his death -- he argues that a board decision, not genetics, should determine succession (but it's certain that corporate governance is not his ruling principle). In fact, the bulk of the companies' stock in Sumner Redstone's estate is slated for his grandchildren.

It's too bad that Shari Redstone isn't more valued by her father. A workaholic known to go days on a few hours' sleep a night, Sumner calls her "relentless" and a "clone" of himself (when he's in a good mood). She practiced as a lawyer before raising the three children she had with ex-husband, Rabbi Ira Korff. She's a dealmaker and a creative force, though her struggles to revive a chain of movie theaters in a world of interactivity sometimes seem for naught -- the industry is not looking up.

Is it even worth the battle for Shari? It seems so; thus far she has fought tooth and nail to stay on the boards of CBS and Viacom, and to protect the company's assets against her dad's more personal endeavors. Despite all appearances, Daddy can't live forever, and perhaps the board that's left when he's gone will favor her efforts. One thing's for sure, though: this inheritance of political infighting and dysfunction is one I'm glad I don't have coming to me.
