Apple has also joined in the wagon of pulling star power to promote its brand and products. The latest ad campaigns of the mobile technology giant have roped in Hollywood actor Samuel L. Jackson and the "New Girl" sensation Zooey Deschanel. The approach is quite unprecedented from Apple, which has normally based its ad thrusts on the beam of illuminating how its products are useful to the everyday ordinary users.

As much as the "Get A Mac" campaign featured stars Justin Long and John Hodgman, the icons were not the main focus of the ads. Commercials done previously featuring Siri iPhone 4S virtual assistant, showed Siri assisting a jogger in answering e-mails on-the-go, and a busy mom calculating some recipe ingredients figures, as well as a blind lady scheduling the next appointment.

Also notable in the previous ad concepts by Apple was the projected focus on the devices themselves and the content and components that Apple products users will have at their disposal.

"Apple's use of celebrity endorsements for its ads is a departure from the company's previous commercials, which were focused on the iPhone itself, highlighting one of its features or apps. Apple also had two ads promoting Siri, including one featuring Santa in December," noted Daniel Ionescu on PCWorld.

It is true that in the new ad spots, Siri still comes out assisting with solving everyday problems but the major difference notable in the new ad concept is that the everyday problems happen to be those of famous people. This may be well viewed as a paradigm shift in the mobile technology giant's conceptualization of advertising. Yet categorizing Apple advertising approach based on the single new ad campaign may be preposterous. In the new spots, Jackson's advert is a co-branded thrust for Verizon's Version of the iPhone. On the other end Deschanel is "advocating" for the 4S on Sprint's network.

The end of the ad campaigns features AT&T, Sprint and Verizon branding and the lack of a career name on the iPhone displayed in the videos suggests that the infomercials were made by Apple working with their advertising agency TBWAChiat|day.

Even though Apple has not published the videos through its regular channels, many viewers have already recorded the ads videos.

In another development related to the Apple products ads, a New York man has recently submitted a class-action suit against Apple. The complaint states that Apple ads have been misleading and deceptive about what the iPhone 4S virtual assistant can really do. According to the report published by Washington Post, the complainant has labeled Apple ads as "fiction" stating that there is a huge disparity between what the ads claim the devices can do and what the devices can actually do.
