What happened

If you’re thinking about moving house or just feeling nosy about your neighbours, your first port of call may be an online property marketing site: Rightmove and Zoopla in the UK, Zillow in the US or Magic Bricks in India.

Why it matters

They offer 3D plans of their properties and a video walkthrough, sometimes with added interactive tools.

Common ground

It all seems very modern – yet it turns out, at least one pioneering London estate agent was offering its clients 3D visual walkthroughs long before the advent of commercial photography.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
