Media tycoon Rupert Murdoch lashed out at Google over the weekend, accusing the internet search giant of encouraging online piracy.
"Piracy leader is Google who streams movies free, sells adverts around them. No wonder pouring millions into lobbying," said Murdoch on Twitter.
The News International owner later added that he considers Google to be a great company doing many exciting things, but that he thinks the firm should take a more active role in combatting piracy.
"Just been to Google search for Mission Impossible. Wow, several sites offering free links. I rest my case," said Murdoch.
Murdoch is, of course, no stranger to controversy. He recently came under attack after the News International phone-hacking scandal broke, although he has insisted he did not know at the time of the unethical practices going on at the firm.
One Twitter user, Johannes Muije, argued Murdoch was in no position to be pointing fingers.
"You know, you're absolutely right. I should totally be listening to a lecture from the guy responsible for phone hacking," he tweeted at Murdoch.
In response to Murdoch's comments, Google has argued that it respects copyright.
"We've worked hard to help rights holders deal with piracy. Last year, we took down five million infringing web pages from our search results and invested more than $60 million in the fight against bad ads," a Google spokesperson said.
"Like many other tech companies, we believe there are smart, targetted ways to shut down foreign rogue web sites without asking US companies to censor the internet".
Murdoch has hit out at Google in the past, branding it, along with Microsoft and other news aggregators, as thieves who "take stories for nothing" by republishing links to content on their sites.
Soon after, Murdoch effectively blocked such sites from linking to specific content on The Times and Sunday Times when he hid the news sites behind a pay-wall.
