To me it feels like a case of a network sabotaging its own show. Step 1: be incredibly inconsistent with air times and play around with dates, step 2: dumb the program to capture a larger audience by making sweeping changes, introducing younger presenters and disturbing a well-oiled team that people have come to love, step 3: ax show when ratings fail to climb because bogus strategy didn't work.<p>A terrible loss for archeology, not just in the UK. Twenty seasons is a massive achievement though.
