You are kidding right? Apple is known to advertise pretty strong for all their products. Do you watch movies or tv shows? Apple puts their products in more movies than any other brand. They make the best products yes, but they also advertise like crazy.
you are kidding right? Apple's advertising budget is peanuts in comparison with Samsung or any other tech giant.
Product placement in films is never paid by Apple (or so they claim), there are also never official partners or sponsorships.
Yes under Tim there is more advertising, but still not much in comparison with others.
