Until recently, I used to play spot the voiceover in the ad breaks during ITV programmes. Now, more and more, I find myself playing spot the ad. You expect ad breaks that consist of nothing but trailers during regional opt-out documentaries, even if they're rather good ones about canals presented by Timothy West. However, even a high-rating Saturday night show like Al Murray's Happy Hour can struggle to pull in the advertisers. OK, the show has a sponsor, who must be paying a fair bit towards the upkeep of the old LWT building, but absence of other advertisers and the preponderance of puffs for things starring Robson Green doesn't bode well for the financial health of the light channel, IMHO.
