By the early 1970s the US grocery industry recognized that machine-readable product codes scanned at checkout could dramatically cut labor costs, pricing errors and checkout time, but the technology faced a structural deadlock no individual company could break on its own: a retailer investing in expensive scanning equipment gained nothing unless a critical mass of the products on its shelves already carried a compatible code, while a manufacturer had no reason to print a code on its packaging unless enough retailers had already installed scanners capable of reading it.

Rather than leaving individual companies or trade associations to negotiate bilateral standards or wait for market forces to resolve the deadlock organically, the grocery industry formed the Ad Hoc Committee for a Uniform Grocery Product Identification Code, a neutral cross-industry body tasked specifically with selecting one single symbol format the entire industry would commit to simultaneously, removing any individual company's need to bet on a standard before the rest of the industry had chosen the same one.

The committee broke the deadlock by picking one mandatory standard, the UPC symbol, making adoption collectively rational.

Retailers wouldn't buy scanners without barcoded products, and manufacturers wouldn't label without scanners, so neither moved.

A neutral committee selected one symbol, eliminating the risk of backing the wrong format.

With a single standard, each adopter strengthened the case for the next, creating a virtuous cycle.

The synchronized commitment made adoption collectively rational even though it was individually risky.

When a technology needs two-sided adoption, a neutral body can pick one standard everyone commits to, removing the risk of betting on a loser.

An industry-wide committee picked one mandatory symbol in 1973; by 1989 barcodes covered over half of all US grocery sales. The UPC standard became close to universal across global retail and expanded far beyond groceries into nearly every physical product category, with IBM's own official history and outlets including History.com crediting the 1973 committee decision directly for resolving the adoption deadlock that had stalled the technology.
