It's been a month since the powerful media mogul Rupert Murdoch started giving us an insight into his 80-year-old mind.

When he first joined Twitter on 31 December no-one could quite believe it.

A man feared by by many politicians for his influential position as owner of News Corporation, which runs a large amount of the world's popular media including The Sun, Fox, and Sky, was about to broadcast his humble thoughts directly to anyone who would listen.

It turns out Murdoch is more moaner than monster.

International Business Times UK looks at some of his tweets' targets.

People on Twitter

"Why can't we have sensible tweets.You're mainly just crazy and fun to read.No loss of sleep here."

Barrack Obama

"So Obama has thrown in his lot with Silicon Valley paymasters who threaten all software creators with piracy, plain thievery."

Mitt Romney

"Romney tax uses long-term legal loophole. 'carried interest' makes all fund managers rich.Time both parties stopped selling out to Wall S"

Google

"Piracy leader is Google who streams movies free, sells advts around them.No wonder pouring millions into lobbying."

Cinema snacks

"Agree about cinema prices which out of our control - but even more offensive are prices for popcorn and sodas."

Europe

"American economy looking better. At least short term. Meanwhile Europe looks slow motion train wreck.Hope I'm wrong."

Mitt Romney (again)

"When will Romney get a manager to prepare him? Fancy not being ready for questions about taxes or felons! Damaging."

Angela Merkel and the Euro

"Merkel the boss and wrong.Euro always a huge mistake, but free trade EU okay without one currency."

Anti-SOPA bloggers

"Seems blogosphere has succeeded in terrorizing many senators and congressmen who previously committed. Politicians all the same."

Casinos and "theories"

"Normally disapprove of casinos,but hitting 16s and 17s lot of fun.To hell with theories!"
