Many viewers and analysts have been left stunned by the nature of the hour-long interview, with one public relations expert comparing the footage to "watching a man in quick sand".
Crisis consultant Mark Borkowski said it would likely "haunt" the duke in future and could impact his association with some charities that he works with.
He added: "I've never seen anything so disastrous. For students of PR, that is how not to do it. It was like watching a man in quick sand and unfortunately, I don't think anyone would have thrown him a line to get him out."
Mr Borkowski said the duke should "keep a low profile", switch off his phone and not look at
the papers on Sunday, which are dominated by the fallout from the interview.
