History & Background

The institution behind merriam-webster.com has roots stretching back nearly two centuries. In 1831, brothers George and Charles Merriam established a printing and bookselling operation in Springfield, Massachusetts, naming it G. & C. Merriam Co. After the death of celebrated lexicographer Noah Webster in 1843 — whose foundational work "An American Dictionary of the English Language" had first been published in 1828 — the Merriam brothers acquired the rights to that landmark publication. The first Merriam-Webster dictionary was published on September 24, 1847, priced at $6.00 per copy, and drew praise from prominent figures of the era including President James K. Polk.

In 1964, Encyclopædia Britannica, Inc. acquired the company as a subsidiary. The firm adopted its current legal identity, Merriam-Webster, Incorporated, in 1982. As the internet grew into a primary reference medium, the company extended its content online, eventually making merriam-webster.com the dominant face of the brand for most users worldwide. This unbroken heritage — spanning more than 190 years of continuous operation — makes it the oldest dictionary publisher in the country.
