I think that Apple
had a stronghold on the market before, during, and after Christmas with showing off iPods and marketing their colorfull, younger-audience inspired iPod adds. And they did a good job of it. Who
doesn't know what an iPod is by now? Hell, the word "iPod" is almost becoming synonymous with the words "Mp3 Player". I just wish I had invested money into Apple before the holiday season...
But now is time for some change. Apple is going to start declining in market share if they don't start up marketing campaigns on things like the ones mentioned before; iMacs, PowerBooks, iBooks, Mini's, etc. Apple could seriously take off from the popularity of the iPod as a firm-ground unto the population.
I think that the idea of bringing back the Switch campaign again in a different form wouldn't be the greatest idea. Sure, it might grab some people, but I think that Apple now has enough audience recognition to just advertise as a singular company, with no intervention into the realm of "switching". They could market their great and superior product to the masses in just the new-age way they did with the iPod commercials.
Just think of the impact an Apple-style iMac ad would make...
EDIT: Oh, and the Think Different advertising. I personally like the idea, but I don't think it would appeal to the masses again. It's just a little too old to bring back now.
