Rebranding of Pepsi

I was watching TV the other day and came across this commercial for what I thought was an airline company. (Maybe Korean Airlines?)

It turns out that Pepsi had rebranded themselves (again?). Although I liked their commercial, I can't believe they changed their brand so much. o_O There's three different logos between Pepsi, Pepsi Max and Diet Pepsi. Weird... their bottle is super phallic too. Why?
