Nick Jr. was first broadcast in the UK and Ireland from 1993, during the daytime hours from 9am – 3pm on the main Nickelodeon UK channel. It was joined soon by CBBC on Nickelodeon from 1996 which showed CBBC pre-school programming, it was broadcast from 9am – 10am and 2.30pm – 3.30pm.
In 1999, CBBC on Nick was dropped and the Nick Jr slot was spun off into its own channel although the slot on Nickelodeon continued until July 2000, initially broadcasting on channel 606 on Sky, and from 6am to 12 midday alongside Sky Sports 3 on analogue satellite, although this schedule would sometimes be altered if sports were being covered in the early morning.
When it first properly aired it was presented by Face. In 2001 MTV Dance started broadcasting during its downtime hours after it was spun off from MTV Extra. MTV Dance acquired its own separate channel in 2002 and both channels have since extended their broadcasting hours.
