The issue of phone hacking comprised only minutes of the four-hour long hearing on Wednesday. The elder Murdoch condemned the practice again, saying "I don't believe in using hacking."
"I don't believe in using private detectives or whatever," Rupert Murdoch said. "I think that's just a lazy way of reporters not doing their job, but I think it is fair, when people are held up as great, or had themselves held up as iconic figures or great actors, that they be looked at."
According to Hugh Tomlinson of the Queen's Council, the now defunct News of the World allegedly hacked the phones of 4,791 people, from stars to crime victims, to get juicy stories -- all with the encouragement of top editors at the paper and aided by some in the police force.
Rupert Murdoch made a rare apology in British newspapers last year at a parliamentary hearing. The Murdochs appeared before a parliamentary committee last year for the first time, during which the elder Murdoch was attacked with a shaving cream pie.
The Murdoch name has been synonymous with News Corp. even before it was incorporated in 1979. Rupert Murdoch, the only son of Sir Keith Murdoch, took over his father's newspaper publishing business, News Limited, after the elder Murdoch passed away in 1952.
The Oxford-educated media mogul took over his father's newspaper business, News Limited, in his native Australia when he was 22, according to the BBC. Reportedly in good health since being diagnosed with "low grade" prostate cancer in 2000, he has formerly reportedly insisted that his eventual successor have the Murdoch name.
Murdoch published a full-page apology in British newspapers last year about alleged phone-hacking by journalists at his tabloid, the News of the World.
The 81-year-old Murdoch has six children, three of whom are directly involved in his media empire. Murdoch married Wendi Deng, 43, his third wife, in 1999. They have two young daughters, Grace and Chloe.
