Sherlock's third series has broken DVD pre-order records.

The popular BBC drama, starring Benedict Cumberbatch and Martin Freeman, broke the record for the most customer pre-orders for a programme yet to finish broadcasting.

In addition, the boxset of Sherlock series 1 and 2 took a place in the top ten best-sellers of 2013 in the TV titles chart, according to data from BBC Worldwide.

Sherlock series three may be ending, but series four and five are on their way...

Fret not, those of you worrying about Sherlock's imminent disappearance from Sunday nights (oh, series three, we hardly knew you!), because Sherlock is confirmed to be returning.

We've known series four was a sure thing for some time now, but it's reassuring to hear it straight from the horse's mouth. By horse, we mean Sue Vertue of course, the wonderful producer who channels the show's collective talents and actually makes it happen.
