What's the message?; are current UK adverts meant to sell us something make us recall the - er - 'good times'?

Just watched Coronation Street for the first time in months, and was made to watch Twiggy harp on about a store from it's beginnings to where it is now, with nostalgic pictures. Over the weekend, saw a couple more, from Hovis (AD79 to 2009) to Milky Bar - with all the kids of the programmes flashing by...calling at Persil (the many designs of their boxes), and other old-stylee products. Is this their answer to the recession - press the 'nostalgia' on? Noticed the ads. coming on during the dross of Saturday night viewing, or during the soaps. Does this mean their 'target' are socio-economic C2DE's - who, thanks to the actions of the present government, along with other professionals who should know better - who either haven't two farthings to rub together, or can only manage to get the lowest band of Sky telly?
