A web enhancement is a bonus expansion to a role-playing game product, that can be read and/or downloaded from the website of the company that published the role-playing product it is associated with.
The web enhancement concept was created by Sue Weinlein Cook, who was an editor at Tactical Studies Rules, Inc. (TSR) and later the brand manager at Wizards of the Coast (WotC). There is a common belief that web enhancements are created from content cut from the published products, but many of them are specifically commissioned as bonus material.
