Yahoo Groups
Group messages can be posted and read by e-mail or on the Group homepage, like a web forum. Members can choose whether to receive individual e-mails or daily digest e-mails, or to read the posts at the web site.
Some Groups are simply announcement lists, to which only the Group moderators can post, while others are discussion lists.
As well as providing e-mail relaying and archiving facilities for the many lists it hosts, the Yahoo! Groups service provides additional functions on the web site, such as voting and calendar systems and file uploading. The basic mailing list functionality is available to any e-mail address, but a Yahoo! ID is required for access to other features.
Yahoo! Groups competitor is Google Groups.
History
Yahoo! Groups was launched in 1998 as a logical extension of services that had already been developed by Yahoo - message boards, calendars, profiles.
Unlike previous Yahoo products, this product was designed to allow much deeper levels of user control over creation, membership and overall direction of communities. Development was led by Doug Hirsch (product management) and Matt Jackson (lead engineer), both of whom have since left the company.
Yahoo! Groups quickly grew to be one of the largest traffic-generating products within the Yahoo! network of services; even today the site is typically one of the Top 5 page-view generating sites across the Yahoo network.
In 1999, Yahoo acquired eGroups.com, one of the most popular mailing list products at the time.
About 8 months later, Yahoo merged the eGroups.com functionality with Yahoo Groups, resulting in some complaints from users of both services.
Yahoo Groups languished between 2000 and 2005. In 2001 Yahoo! deleted adult groups from its search directory, making it very difficult to locate Yahoo! groups with adult content.
A Yahoo! user who wishes to find a group with adult content must therefore either know the exact name of the group, or attempt to find it by using a search engine or one of several online adult group directories. This has created what some view as an "underground" atmosphere for Yahoo! adult groups.
While it is unclear whether the intention of Yahoo! was to diminish the number or merely the easy availability of these groups, adult groups on Yahoo! have continued to increase. No edit function except delete.
