The 7.30 kids' spot on GMTV was initially a fully-fledged spot called Alarm Alert with Simon Parkin, but it was one of the earliest casualties of the failure of the original GMTV, not least because every kid in Britain was watching The Big Breakfast, so they soon jettisoned that and just ran cartoons instead. Then GMTV bought Power Rangers and every kid in Britain abandoned The Big Breakfast and watched that instead.
Though they broke up episodes into several small chunks spread across a whole week. Ridiculous. I always watched it on Sky instead.
