That included support from largest shareholder Fox, which controls a voting stake of 37.19 percent in Sky.
The deal - worth £11.7 billion ($15.4 billion, 13 billion euros) - would see entertainment group 21st Century Fox buy the 61-percent of pan-European satellite TV company Sky it does not already own.
Later on Thursday, shareholders voted in favour of the re-election of Murdoch´s son James as chairman.
Fox's US$15 billion bid for Sky is now with United Kingdom competition watchdogs.
More than 28% of shareholders voted against Mr Murdoch's comeback as chairman last year, four years after he stood down from the position in the wake of the phone-hacking scandal at the News of the World.
In a stock exchange announcement detailing the AGM vote, Sky said: "The board is pleased that the majority of resolutions have been passed with a high level of support from shareholders".
The shareholder, Hugh Lawson, said: "I think the board lacks independence".
This week the Competition and Markets Authority (CMA) outlined how it will examine the deal and the impact on media plurality and broadcasting standards in the United Kingdom and invited submissions for the six-month investigation.
In response, Martin Gilbert, Sky's deputy chairman, pointed out that Sky's board had formed an independent committee to evaluate the terms of 21st Century Fox's takeover, which he said had met 11 times since the takeover approach was tabled in December a year ago.
Asked by members of the Culture, Media and Sport Select Committee about that decision, Ms White said Ofcom had carried out a thorough review of recent activity at both 21st Century Fox and also at News Corporation - the owner of The Sun, The Times and The Sunday Times - which until 2013 were both part of the same company.
Sky's subscriber base swelled by a 160,000 new customers in the three months to late September, up 51 percent on a year earlier, it said in a trading update.
European pay-TV giant Sky, facing a possible takeover by Rupert Murdoch´s 21st Century Fox, announced Thursday a surge in subscribers on keen demand for cult U.S. series Game of Thrones.
Jeremy Darroch, Group Chief Executive, said that the good revenue growth and excellent profit growth was achieved against the backdrop of pressure on consumer spending and lower spend on United Kingdom television advertising.
He said the first series of Sky's home-grown drama Riviera achieved 20 million downloads, while Game of Thrones had become the most watched series ever on Sky. The company launched new streaming services in Spain and Switzerland in the quarter.
