Time Warner reported a 3 percent jump in quarterly revenue, helped by the popularity of “Game of Thrones” and other shows on its HBO network. Time Warner shares were down 13 percent before the bell on Wednesday, a day after Rupert Murdoch’s Twenty-First Century Fox abandoned an $80 billion bid for the company. Net income from continuing operations attributable to Time Warner common shareholders rose to $843 million, or 94 cents per share, for the three months ended June 30 from $698 million, or 73 cents per share, a year earlier. On an adjusted basis the company earned 98 cents per share. The company said the fourth season of “Game of Thrones,” which ended in June, was the most watched season of an original series in HBO’s history. The Emmy award-winning fantasy epic had an average gross audience of 19 million viewers.
