Carlton Video was the video service of the British Carlton ITV network and it was run by Pickwick Entertainment as well.
Carlton had (just like adult videos) some interesting children's videos including Tots TV, the Beatrix Potter cartoon series, Bananas in Pyjamas, and many more.
You see the "Carlton" letters up in your face and moving then quickly zooms out into "CARLTON VIDEO".
Exterme High. All the big letters of "CARLTON", the gross background colour and the whooshing sounds will scare someone quite badly.
