Grant made the announcement on his 2DayFM radio show Breakfast with Em, Grant & Ed earlier this week.
“I’ve got a big announcement guys, Family Feud is wrapping up," he said.
“It’s obviously been a huge success for myself and 10. We only thought we would get two years out of it.”
Grant, who has hosted 1200 episodes of the family game show, offered up a reason as to why the show failed.
“We’re probably guilty, if anything, of driving it into the ground a little bit too early,” he admitted.
“Six days a week, twice a day, plus All Star episodes, we might have squeezed that lemon a little bit too much.”
However, the cancellation of Family Feud doesn't mean Denyer is leaving the screen too.
According to the host, Channel Ten have “big new projects” they want him to work on.
