Buzzwords and Catch Phrases

It's interesting how many of today's brand name products have a handy little catch phrase associated with them. I remember the old Datsun ads when I was a mere lad that said, "drive a Datsun, then decide". It was catchy and you remembered it, now you just need to remember what a Datsun is, or was. I guess it wasn't catchy enough to sustain the brand even though it now goes by a different name in the U.S. In the spring time you start to hear about Guinness and that it's not only an Irish stout but also a food along with erin go bragh and welch allyn. Popular soft drinks boast "just for the thrill of it" and "wouldn't you like to be a pepper too?" hit the airwaves fast and often, especially when the warmer weather approaches. Cookies, cakes, television networks, cars, trucks, computers(are you a PC?), and even the halls of higher learning have catchy sayings that when spoken you know without being told which college it is(the Fighting Irish of ....). People have made careers out of these phrases and jingles and the like, not to mention millions in sales for the respective clients, because people remembered the slogan or song and it stuck in their mind when they were shopping and they bought it based partly on recognition of the brand. Are we still the Pepsi Generation?
