I've mentioned BBC age discrimination previously. It seems that, barring exceptional circumstances, CBBC presenters over the age of about 30 are simply surplus to requirements.

Two of CBBC's former presenters were, however, allowed to appear on TV for a short while yesterday afternoon, as part of the 25th anniversary celebrations. But we're unlikely to see older presenters again for quite a while. Ed Petrie (now aged 32) made a comeback last year and continuing into 2010, but that was maybe just as a stopgap measure until younger presenters such as Chris Johnson could be found and trained up.
