It started with a problem.
Carl Magee, a newspaper editor and attorney in Oklahoma City, patented the first coin-operated parking meter in 1935. The City of Oklahoma City installed the first 174 Park-O-Meters on July 16, 1935. Magee invented the meter in response to a request from the Oklahoma City Chamber of Commerce, which was concerned that downtown workers were occupying parking spaces all day, preventing customers from parking near shops. The intent was to increase turnover of street parking spaces — pricing time to discourage all-day parking by non-shoppers. The Smithsonian holds an early Park-O-Meter in its collections.

The parking meter applied a pricing mechanism to a previously unpriced scarce resource. Before meters, street parking was allocated by first-come, first-served availability with no cost beyond time. Meters added a time-based cost, which discouraged long occupancy. This changed the nature of the resource from a public good to a priced service. The revenue generated went to the city. The policy debate about parking pricing — whether it serves commerce, reduces congestion, or simply taxes motorists — has continued for ninety years without resolution. What is undisputed is that the meter introduced a market mechanism into a previously unpriced space.
What a builder can learn.
Our interpretation: the parking meter illustrates how adding a price to a previously free resource changes who uses it and how. When something is free but scarce, it is allocated by willingness to wait or arrive first. When it is priced, it is allocated by willingness to pay. For a business builder, this distinction matters in any situation where a resource — time, access, attention, space — is being provided free of charge. Pricing it changes both who uses it and the signal about its value.
A door still open.
A hypothesis worth testing: if a small business that currently provides a service or resource for free — a consultation, a download, a tool — added a minimal price, would the composition of users change (fewer who are merely curious, more who are genuinely in need) without the total number of engaged users decreasing?
Which parts of your business are provided for free primarily out of convention rather than because free is the most effective price — and what would happen to demand quality if you charged a small amount?
