Scores of listeners and viewers e-mailed and phoned in, with one accusing journalists of being "on the verge of hysteria".
Programmes such as BBC1's news at 6pm and The World at One on Radio 4 were attacked for devoting too much time to Thursday's announcement at the expense of other world stories.
Simon Whomsley, a viewer, said: "Camilla and Charles to marry; Pope returns home; North Korea has confirmed it has nuclear weapons.
"This is the order the news was presented tonight! Absolutely amazing."
A spokesman for the BBC said: "We recognise that not all viewers are interested in stories relating to the Royal Family, but equally there is a significant audience who do wish to be informed of such decisions."
The news special pulled in an audience of 4.1 million - the second most popular programme in its slot after ITV's Emmerdale.
