Geocities was an online collection of metropolises, each with their own neighborhoods built around shared interests. The city metaphor helped make a whole new group of users understand the world wide web for the first time. At its peak, it was the third most popular destination on the internet, but it quickly fell out of fashion as the web became more commodified and professional. Before it shuttered, a few digital archivists scooped up as much data as possible before all that early internet experimentation could be deleted.

But back in the 80s, most people didn't know this remarkable fact about peat. If anything, bogs were seen as scary places to be avoided and thus we tended to not take care of them. But that’s changing. For the Love of Peat Buy The 99% Invisible City! Subscribe to SiriusXM Podcasts+ on Apple Podcasts to listen to ad-free new episodes and get exclusive access to bonus content.

An address is something many people take for granted today, but they are in fact a fairly recent invention that has shaped our cities and taken on great political importance. Deirdre Mask is the author of The Address Book: What Street Addresses Reveal About Identity, Race, Wealth, and Power, which looks at all the ways the world has changed since the popularization of street addresses during the Enlightenment. The book examines how addresses impact wealth and poverty, and how they serve as proxies for our most contentious debates. Mask also explores a digital future where we aren't reliant on the numbers on our homes to tell us where we are or where we're going.
