  ===Adaptation schedule and episodes===
  After ''Game of Thrones'' began outpacing the published novels in the sixth season, the series was based on a plot outline of the future novels provided by Martin and original content. In April 2016, the showrunners' plan was to shoot 13 more episodes after the sixth season: seven episodes in the seventh season and six episodes in the eighth. Later that month, the series was renewed for a seventh season with a seven-episode order. Eight seasons were ordered and filmed, adapting the novels at a rate of about 48 seconds per page for the first three seasons.

  The first two seasons adapted one novel each. For the later seasons, its creators see ''Game of Thrones'' as an adaptation of ''A Song of Ice and Fire'' as a whole rather than the individual novels; this enables them to move events across novels, according to screen-adaptation requirements.
