An anonymous reader writes: Google's I/O 2015 conference opened with a surprise announcement: that Chromecast, Android TV, and other Android devices will soon be able to offer HBO Now. "The announcement marks the end of a 7-week exclusive that Apple had on HBO's stand-alone streaming and on-demand video service," reports Digital Trends, and it also further weakens the exclusivity of cable TV packages. "Traditional TV subscriptions are slowly starting to slip," one newspaper reports, "as more people watch online video." Other online streaming sites are already confronting the popularity of HBO's "Game of Thrones" series, with Netflix already experiencing a 33% dip in their online traffic during the new season's online premiere and Amazon rushing to discount their "Game of Thrones" graphic novels, and the turmoil seems to be continuing in the online video space. "Shortly after the premier of the new season, HBO Now seems to have taken the top spot when it comes to internet traffic," reports one technology site, "causing a huge dent in Netflix's attempt to make it to the top."
