'Game of Thrones' renewed for two more seasons

 LOS ANGELES: Hit HBO television show 'Games of Thrones' was renewed for two more seasons Tuesday, two days after its latest series opened with a bang that crashed the broadcaster's online app.

Sunday's fourth season debut drew 6.6 million viewers, the most for the pay-channel since the finale of HBO cult hit 'The Sopranos' was watched by 11.9 million people in 2007, the broadcaster said. Its creators David Benioff and D.B. Weiss "along with their talented collaborators, continue to surpass themselves, and we look forward to more of their dazzling storytelling," he said. HBO Go, an online app that allows viewers to watch shows any time, crashed Sunday as tens of thousands tried to log on to watch the show.

Since its debut in 2011, the HBO drama based on George R.R. Martin's best-selling novels about a struggle for power between feuding clans in seven mythical kingdoms has won a devoted global fan base -- President Barack Obama reportedly among them -- to establish itself as the star of the US cable channel's stable.

The series has wowed critics with its densely-layered plot, lavish production values and a readiness to kill off, invariably in gruesome fashion, protagonists who had hitherto seemed integral to the show.

Four words - 'No one is safe' - have become the unofficial catchphrase for devotees of the series. Guessing which character may soon meet his or her maker is all part of the fun.

An infamously bloody episode in Season 3, involving a massacre at a wedding party, was one of the most talked about and tweeted television events of 2013. YouTube videos capturing the shock of unsuspecting viewers watching as the on-screen slaughter unfolded rapidly went viral. All the signs are that fans of the show will not be disappointed by the 10-episode Season 4, which debuted in the US on Sunday before being screened in different markets worldwide over the following days and weeks.
