Britain's phone-hacking scandal erupted last summer after it emerged that journalists at Rupert Murdoch's News of the World routinely eavesdropped on cellphones' voicemail boxes in order to score scoops.

The probe has since grown to include allegations of computer hacking and bribe-paying across the British media — and beyond.

Here are key developments in that scandal:

November 2005: News of the World royal reporter Clive Goodman writes story saying Prince William has a knee injury. Buckingham Palace complaint prompts police inquiry.

August 2006: Goodman arrested along with private investigator Glenn Mulcaire for suspected hacking into voicemails of royal officials.

January 2007: Goodman jailed for four months; Mulcaire given six-month sentence. News of the World editor Andy Coulson resigns but insists he had not known about the hacking.

May 2007: Conservative Party leader David Cameron taps Coulson to be his media adviser.

July 2009: Coulson tells parliamentary committee he never "condoned use of phone hacking."

February 2010: Parliamentary committee finds no evidence that Coulson knew about phone hacking but states it's "inconceivable" that no one apart from Goodman knew about it.

May 2010: Cameron becomes prime minister; Coulson named communications chief.

Jan. 14, 2011: British police reopen investigation into phone-hacking charges against News of the World.

Jan. 21: Coulson resigns from Cameron's office amid claims he had sanctioned phone hacking. Coulson continues to deny any wrongdoing or any knowledge of hacking.

April 15: Judge allows actress Sienna Miller and three others to proceed with lawsuits against the newspaper despite an ongoing criminal investigation.

May 13: Miller's lawyer says lawsuit settled for 100,000 pounds (about $165,000 at the time). Since then, News International has reached settlements with several others to avoid trials.

June 30: British regulators give News Corp. tentative approval to take full control of satellite broadcaster British Sky Broadcasting.

July 4: The Guardian newspaper reports that News of the World journalists hacked into voicemails left for murdered schoolgirl Milly Dowler, and gave her parents and police false hope she was alive by deleting messages when the mailbox became full.

July 8: Coulson and two other men are arrested in the widening police inquiry.

July 11: News Corp. withdraws offer to spin off Sky News in attempt to save bid for complete control of satellite broadcaster BSkyB. British media report that two other News Corp. newspapers in Britain engaged in hacking, deception and privacy violations that included accessing former Prime Minister Gordon Brown's bank account information and stealing the medical records of his seriously ill baby son.

July 13: News Corp. pulls its bid to take full control of BSkyB.

Nov. 1: Documents show a legal adviser to the company's newspapers warned three years earlier that there was overwhelming evidence that several senior journalists at the News of the World were using illegal methods. The documents bolster claims that high-ranking executives were aware that phone hacking was more widespread than they let on.

Nov. 10: James Murdoch returns to Parliament. He insists he hadn't been told of widespread phone hacking and blames two of his senior lieutenants for failing to warn him of a culture of criminality.
