Nick Katzenberg's vendetta with Peter Parker was an excuse for him to discredit him in any way he could. This resulted in Nick talking to Parker's aunt May and photos he had taken in an attempt to blackmail Peter Parker. He also frequently made harassing phone calls to Mary Jane.
In a Fight with the Hobgoblin
Katzenberg's own sleazy tactics eventually caused him to cross the wrong man: Jason Macendale, AKA the former Hobgoblin, and his apartment was pumpkin bombed as a result. Though Spidey and Moon Knight dragged Katzenberg out of the burning building after he had a heart attack, he still proves to be the sleazy journalist he always was.
He later eventually lost a battle to lung cancer, brought about by his many years of smoking. It was the sad, sorry, deteriating state he was in during his final moments that helped convince Mary Jane Watson to give up her smoking habit.
