Official Doctor Who Twitter

The Doctor Who Twitter account, occupying the namespace of "bbcdoctorwho", was the official Twitter account used by the BBC for Doctor Who-related content.

2011
In January 2011, the Doctor Who Twitter account was created.

Doctor Who: Flux marketing campaign
The Doctor Who Twitter account was involved with the promotion of Doctor Who: Flux, which was designed so that the audience were involved with the narrative of the arrival of the Flux:

On 2 October, 3 October,  4 October, 5 October, 6 October, 7 October, and on 8 October, the account posted "interruptions" - short bursts of distorted footage of the Thirteenth Doctor sending a message. Within the same day, the account posted what appeared to be a transcript of the Doctor saying "can you hear me?" Very quickly after, all of the Doctor Who social media accounts shut down (barring Tumblr, though that account had been inactive since January). In the evening of 9 October, all of the social media accounts returned, posting promo images of the new series as well as giving new details about it. Among the content was the upload of the story The Flux is Coming..., a minisode that had premiered on television earlier that very same day, evidently showing that the "interruptions" where part of the full minisode, in which the Doctor sent out a distress call warning of the arrival of the Flux, indirectly to the viewers.

2022
On 21 May, 2022, the account posted a graph detailing "Everything you can expect from watching 'Legend of the Sea Devils', now in a handy line graph! 📈"
