This blog has looked at 'the end of the high street' a fair bit of late:
Futures Forum: How to revive the health of Sidmouth's high street >>> East Devon MP's on-line survey
Futures Forum: How to revive the health of high streets > "We want vibrant centres in our cities and towns. But not streets lined with identical collections of outlets of the same chain retailers. Think of high streets as community hubs rather than shopping malls."
Futures Forum: Councils and business rates: "their short-term focus on raking in money could end up destroying town centres weighed down by huge tax burdens"
Futures Forum: Save our high streets > by entering them into the Great British High Street Awards 2018
The issue also features in the 'news' section of the Vision Group's website:
Businesses in Honiton are ‘seriously considering their future’ amid pressures facing Britain’s high streets - Vision Group for Sidmouth
Sidmouth loses another high street shop - Vision Group for Sidmouth
The New Economics Foundation has been looking at it too:
