Ridiculous job titles
Client Service people were called Contact Men - until they decided they needed to sound more important than the junior brand manager. Then they became Account Executives, later inflating their titles again to Account Managers. What lies ahead? How many more roles will be called "Director" - perhaps just so the client thinks (mistakenly) that he's talking to people of influence?
The only people with any sense in advertising are Copywriters. Though that name has also changed; correctly it should be a Copywright - as in Wheelwright, Wainwright. Or maybe they just haven't thought up an appropriately ridiculous title. Any suggestions?
