You *might* have heard that The Great British Bake Off is back tonight.
You *might* also have heard that it has now moved over to BBC One.
So last night BBC Two tweeted this lovely message.
BBC One responded with this.
And a lovely exchange was born.
And the public? Of course they joined in.
BBC Two also tweeted this touching final dinner.
Well done, social media managers. C-E-L-E-B-R-A-T-E.
Want to know the people behind these social media accounts? Well, the social media manager for both channels is Rajiv Nathwani. The voice for BBC One is Ben Rawson-Jones, and for BBC Two it is Jonathan OB (who also runs the Twitter account for Waterstones Oxford Street).
