Debenhams lost the plot, it wasn't somewhere that I automatically thought of when I needed supplies. Their stores went on for twenty years following the collapse of C&A. But the only difference to me, between the two companies, was the name above the store.
It's often argued that the internet is the death knell of the High Street. Woolworths went long before the internet took off, BHS it might be argued, was a victim and stores like Owen Owen & Allders were all High Street pre-internet casualties.
The current favourite is The Range, will it too go the way of the others? Or once their founder, Chris Dawson, either takes the money, from selling his company, or pops his mortal coil, The Range will become something different. You only have to look at Tesco, M&S, Sainsburys and others to see that the company changes under a new head honcho. Get it right and the shoppers flock in, but alas, not too many get it right.
