During the quarter, GeoCities named Amazon.com its exclusive bookseller, providing placement throughout its online communities. Amazon also became the premier bookseller on the @Home Network's shopping service, book directories, and search pages, and Netscape Communications made the company the exclusive bookseller in its recently launched Marketplace section of Netscape Netcenter.
The company also attributed some of its success to its continued expansion of its Associate program. The company ended the year with more than 28,000 registered program members. Amazon.com Associate sites link to Amazon.com to offer books of interest to their users.
