Why do most of the characters in the TV shows use flip phones?
Directors prefer to use outdated phones on TV shows because they want to avoid the hassles of obtaining permissions from modern smartphone manufacturers to use them in the show. Also if they use a recent phone it will be free advertising for the phone, and directors certainly don't want that. This is also the reason why you will see characters using fake search engines while surfing on the net.PS: Although this seems pretty legit, it is pretty strange that Macs are shown in many movies and TV shows. Perhaps someone can answer why this rule doesn't apply to Macs.
