What again was the difference between CBBC Choice and CBBC on Choice?
CBBC Choice was the Saturday afternoon strand in the earlier part of BBC Choice's existence and consisted of things like L&K Replay, The Dog and Dinosaur Show, repeats of Rentaghost and Jossy's Giants etc.
CBBC on Choice was the precursor to CBeebies from late 1999, consisting of (mostly) pre-school programming on a three-hour repeating loop throughout BBC Choice's daytime hours. It sometimes delved further into the archives than CBBC on BBC1 or BBC2, for example when it dug out 15 year-old Caterpillar Trail episodes that hadn't seen the light of day for many years, and mid-80s editions of Play School at Christmas time.
The two strands overlapped for a while, until CBBC Choice disappeared in April 2000. CBBC Choice had its own idents, while CBBC on Choice used the regular CBBC idents, but with a standard C|B|B|C| logotype at the bottom of the screen.
