The annual music festival has staged pop acts such as Alesha Green, Pixie Lott and N-Dubz in the past, but John Giddings said that he has not asked for any mainstream pop artists this time around.
Speaking about this year's lineup, Giddings told NME: "This year I've deliberately avoided pop acts, X Factor-type people. I did a couple last year, but I felt a bit uncomfortable about that this year.
"I don't mind having R&B acts on the bill, I don't mind having Professor Green or Wretch 32, but I don't see them as straight pop acts. I think other festivals do straight pop acts and I was backstage at a couple of festivals and they seemed to be full of people I'd seen on TV."
Giddings also explained that he has not intentionally tried to attract an older audience this year by choosing the headline acts Bruce Springsteen, Pearl Jam and Tom Petty.
He said: "Obviously we've got the older acts with Pearl Jam, Tom Petty and Bruce Springsteen, but we've also got exciting acts like Elbow, Example and Noel Gallagher so we've got the best of both worlds.
"It's not deliberate, that's why we've got the variety of acts on the rest of the bill. Our audience is 15-50 and with the likes of Example, Tinie Tempah and The Vaccines, I think we can entertain all age groups."
The Isle of Wight Festival will be staged on June 22-24.
