The first round of the beginnings of reality TV (as we now know it) was fine, it was a new experience and it was full of people with good intentions. The second round declined into being full of self-publicising, get-rich-quick wannabes and it seemingly gets worse every time.
And I never watch live telly, always record it and watch it later to skip any ads. The exception may be BBC's coverage of F1 - but they don't do ads anyway. And I don't watch any reality shows. Ever.
