Which UK channel originally aired BBC's Sherlock?

BBC One originally aired the BBC series Sherlock in the United Kingdom. The modern crime drama premiered on BBC One in July 2010 before later reaching international audiences through broadcasters including PBS in the United States.

Created by Steven Moffat and Mark Gatiss, Sherlock updates Arthur Conan Doyle’s detective stories to the present day. Benedict Cumberbatch plays Sherlock Holmes and Martin Freeman plays Dr. John Watson. The first episode, “A Study in Pink,” introduced the pair and reworked the basic setup of A Study in Scarlet, replacing Victorian London with a contemporary setting filled with texting, GPS, and internet research.

The BBC branding can make the channel question seem deceptively simple. BBC One was the original UK network channel, while BBC HD also simulcast the first episode. PBS’s Masterpiece carried the series in the United States, but it was not the original UK home. Sky One, Channel 4, and ITV were not the channel that first broadcast this version of Sherlock.
