The DVD branding as 2/Entertain is ending as it is merged with BBC Worldwide this spring. The BBC have released a statement which can be seen below.
You will start to see different labelling on BBC product and from the Spring, the 2entertain label will disappear from Doctor Who DVDs. The reverse sleeve will remain as it is now with the old 'BBC' logo so you can match each release with your collection.Doctor Who remains, as ever, an incredibly important property to us and we'll be continuing to bring you a extensive range of great quality Classic Doctor Who DVDs. The name change will not affect the quality of the restoration or the extras which we're excited to be able to bring to fans on DVD throughout the year.
