Bandwagon would be really helpful and useful. If one celebrity is being protected by strict privacy laws, then every other celebrity needs to do the same. Not only are they collaborated by fans, but they also have to be on the constant look-out, so universal appeal could be another one (values about home, family, and everyday life for everyone who joins these efforts).
Flattery advertising media should not be used because it is used to make customers feel special or extraordinary. If a celebrity did this to a customer, it would only defeat their own purposes of being protected by strict privacy laws. Not only that, but flattery is also used to get people to but their product (it would make a celebrity look greedier in a sense).
Lastly, two pieces of media that would at least be effective would have to be universal appeal (family-everyday relations), and band-wagon; because at least band wagon gives a message from celebrities to tell customers to improve their own self in a way. Two advertising media pieces on celebrities at times, that would not have any effect at all, would have to be association and flattery, as they expose celebrities, rather than excluding them.
I just learned about this and it may not be everything you're looking for your essay, but it hopefully gives you ideas about what to write if that's what your learning.
