On January 9, 1998, Disney registered Go.com. Infoseek and Disney Interactive Media Group joint ventured in developing the Go Network, an internet portal. Go.com was launched on January 15, 1999, as a portal with content from ABCNews.com, ESPN.com and Disney.
With Disney's purchase of the remainder of Infoseek in July 1999, the Go Network, Infoseek, the Disney Catalog, Disney Online (Disney.com and DisneyStore.com), ABC News Internet Ventures, ESPN Internet Ventures, and Buena Vista Internet Group were merged into the Go.com company; the company was 72% Disney-owned, with the other outstanding ownership in a tracking stock.
In October 1999, the Go Guides program, a user-edited directory like DMOZ, was launched.
In January 2000, Go.com was forced to abandon its original stoplight logo because of a complaint of similar-looking logos filed by GoTo.com. Concurrently, Go.com company officials announced it was shifting from a general appeal portal to featuring entertainment content. A court later ruled that Go.com had to pay $21.5 million in damages to GoTo.com.
However, in January 2001, Disney announced that it would be closing Go.com and its search engine, laying off approximately 400 employees and retiring the go.com tracking stock.

Since the company retired the stock after the certificate was issued, there is obviously no trading or redemption value. Sold as a collectable only.
