It was announced at Wembley Stadium this morning that the competition will be televised by the BBC and BT Sport, who have secured four-year shared rights beginning in 2014.
Fans hoping that the change in broadcaster from ITV would result in the final being restored to its traditional 3pm slot will be disappointed, however.
Dyke stressed that the later time - which sparked fierce protest from supporters travelling south to attend last season's showpiece between Wigan and Manchester City - is a necessity of the modern game's commercial landscape.
"The final will continue to be held in late afternoon, which is where it's been moved to," Dyke said.
"I'm certainly happy with that because if you look at the viewing figures for the past two FA Cup finals they were much bigger than they would have been had the match kicked off at 3pm.
"The world changed and we had to change with it."
