In August 2016 Martin announced that Universal Cable Productions had acquired the rights to adapt the Wild Cards novels into a television series. In 2017, Martin confirmed he would serve as an executive producer of the HBO television series adaptation of the 2010 novel Who Fears Death by Nnedi Okorafor. Martin also contributed to an upcoming FromSoftware video game titled Elden Ring, writing the worldbuilding aspects for it.
By the end of 2016, all seasons up to season 6 (which premiered on April 24, 2016) had been aired on HBO and all seasons had been released on DVD and/or Blu-ray for home viewing (see List of Game of Thrones episodes). The company confirmed on July 18, 2016 that season 7 would consist of seven episodes instead of the usual ten, and would premiere later than usual, in mid-2017, because of the later filming schedule. This was necessary in order to be shooting during the winter season in Europe. Season 7 was expected to air in mid 2017. The first footage from the season was revealed in a new promotional video that featured clips from its new and returning original shows for the coming year on November 28, 2016, showcasing Jon Snow, Sansa Stark and Arya Stark. Like the previous season, it would largely consist of original content not found in Martin's A Song of Ice and Fire series, but also adapts material from the upcoming sixth and seventh novels: The Winds of Winter and A Dream of Spring.
For season 8, in November 2016, President of Programming Casey Bloys indicated that he had had preliminary discussions about a prequel spinoff to the Game of Thrones series with Martin. In May 2017, HBO commissioned five screenwriters – Max Borenstein, Jane Goldman, Brian Helgeland, Carly Wray and Bryan Cogman – to develop individual spin-offs. All of the writers are to be working individually with Martin. According to Casey Bloys, Martin is co-writing two of the four announced scripts. The first episode of season 8 was broadcast on April 14, 2019. This season had a total of six episodes.
In December 2016, Martin was a key speaker at the Guadalajara International Book Fair 2016 in Mexico where the author provided hints about the next two books in the series A Song of Ice and Fire.
