anyways, rai yoyo was a kids channel in italy launched in 2006 as raisat yoyo, then renamed to rai yoyo in 2010, and moved to the same name with the 2nd y being lowercase in 2017.
rai gulp was another kids channel launched the year after that channel.
rai ragazzi was yet another kids channel launched in 2010.
