Read this: BT vs Sky: A New Brand Image for Vision -

Summary: One of the things BT has done to make its Vision service more marketable is create a new logo and colour scheme that will aim to forge the service a distinct identity, separate from associations between BT and outdated terrestrial television services. The new logo features an ambiguous triangular shape that falls somewhere between the V in Vision and the play button on a TV remote control. BT hopes that this new logo will add personality to its Vision service. - press-release-service.co.uk
