News Corp chairman and chief executive Rupert Murdoch has accused internet giant Google of aiding film piracy.
The Australian-born media mogul used his recently activated Twitter account to blast the search engine, branding it a "piracy leader".
"Piracy leader is Google who streams movies free, sells advts around them," Murdoch wrote.
A short time later he added to the rant, saying film making was "risky as hell", with piracy hurting actors and writers.
Murdoch then added: "Google great company doing many exciting things. Only one complaint, and it's important.
"Just been to google search for mission impossible. Wow, several sites offering free links. I rest my case."
That was a reference to the latest Tom Cruise movie Mission: Impossible - Ghost Protocol.
The comments were among Murdoch's most outspoken since launching his Twitter account on January 1.
He's used the social networking site to pass judgement on a number of subjects, ranging from serious comment on US politics to his own error-prone typing.
"Re complaints about my spelling! Problem is my pathetic typing. Sorry, if anyone really cares," the media mogul wrote on January 10.
