Series 1 (Class)

The first series of Class was announced on 1 October 2015 as an eight episode young adult spinoff set in Coal Hill School, that was streamed on BBC Three in 2016 and later aired on BBC One in 2017. This was the fifth Doctor Who television spinoff after K9 and Company, Torchwood, The Sarah Jane Adventures, and K9 and the first spinoff to premiere online rather than on a traditional television channel.

Class was created by Patrick Ness, who previously wrote the tie-in short story, Tip of the Tongue, for the show's fiftieth anniversary. Ness revealed he would exclusively write all eight episodes and that the series would air the following autumn. He further revealed there would be "no Clara" and that Class would "definitely air in America". In an interview with Entertainment Weekly, Ness said he has been asked to bring back many fan favourites since the series was announced, but he wants to create something new. He also confirmed the Weeping Angels would not feature in the series. However, a Weeping Angel made an appearance on the last episode of the series.

In a Radio Times interview Ness stated "the main character is someone brand new" and, with regard to whether the Twelfth Doctor would appear, he teased, "I can neither yet confirm nor deny. But I'm a big Peter Capaldi fan, let's put it that way." Radio Times reported a "source close to the production" said, "don't be surprised if Peter pops up". On 6 September 2016, the Mirror confirmed that Capaldi would show up in the opening episode, along with a gay sex scene further into the series.

The first episode was shown at the Class World Premiere in Shoreditch in London on 20 October 2016.

Class was first uploaded to BBC Three's streaming service on 22 October 2016, with its first two episodes, exactly 10 years after the airdate of Torchwood's first two episodes, Everything Changes and Day One. A BBC One airing followed in the United Kingdom in January 2017.
