The music matriarch were pioneers of the fly-on-the-wall documentary with MTV's The Osbournes, five years before Keeping Up With The Kardashians hit the air.
In a new interview with People magazine, she explained the differences between the two shows, saying The Osbournes had been more natural.
She said: "Ours came organically: Nobody came to us and said, "We've got an idea, will you do this?" With the Kardashians, it's amazing because I look at it in a business point of view and I see those three gorgeous girls influencing a young generation.
"But I also think they should be awarded for manipulation of the press and all of us because they do it brilliantly. I don't think the show is real, which is no problem, but they're manipulating their lives as long as the public is concerned."
She continued: "We never know what's going to happen from one minute to the next with them ... Who would have thought that you could make a book out of silly pictures of yourself! I mean, it's brilliant on a business level – it's absolutely brilliant."
Sharon's mention of a "book of silly pictures" is a reference to Kim Kardashian's recently-released collection of selfies named Selfish.
The Osbournes ran on MTV from 2002 until 2005 and followed the lives of Sharon, husband Ozzy and their children Jack and Kelly. (Their third child, Aimee, chosen not to be part of it.)
Meanwhile, Keeping Up With The Kardashians - produced by Ryan Seacrest - has been airing on E! since 2007 and spawned several spinoff shows including Khloe & Lamar, Kourtney & Kim Take Miami! and Kim's Fairytale Wedding.
