Why can't nickelodeon mention apple products in their shows?

On shows like iCarly, Victorious, Sam & Cat, Ect they have this fake imitation brand called pear phones instead of simply mentioning iphones. Is nick even allowed to mention any real companies? And if not, why?

Its to avoid paying to use their name like how they have ginger fox instead of Britney spears

If Nickelodeon says IPhone or IPod instead of PearPhone and PearPod the Nickelodeon would have to pay Apple because their products are in the show
