Unadvertised by the BBC

I admit to watching little CBBC still but I still usually catch Newsround before neighbours. So why have I seen no adverts for the new series of Grange Hill despite, according to another post it starting two weeks ago? Also why is it only being shown on the CBBC channel? I know the BBC want to stop more grown up programs being shown on BBC1 (there excuse for scrapping Byker Grove) but in the mean time, while they haven’t yet got an in between age range channel they might as well show GH on BBC1 as it must be one of their higher rating programs. And why is there nothing about Grange Hill to be found on the CBBC website? I know its has its own section in the past.
