     Primedia's Auto Enthusiast Portal to Utilize ACP to Satisfy Diverse
            Performance, Scalability and Flexibility Requirements

    BOULDER, Colo., July 17 Primedia's GR8RIDE.com, the
leading automotive enthusiast portal, today announced it has selected
Accumedia, a leading provider of Web publishing and e-business solutions to
develop and manage its Web operations.  By utilizing the Accumedia Convergence
Platform(TM) (ACP), GR8RIDE will have a high-performance system to address its
ambitious online business plans, which will significantly expand the portal's
commerce-based initiatives, including marketplace, event and affiliate
marketing, as well as advertising, sponsorship and promotional activities.
GR8RIDE represents the second Primedia property to work with Accumedia in
recent months, along with the Wedding Network/ModernBride.com family of Web
sites, and strengthens the recently announced strategic relationship between
the two companies.
    The GR8RIDE portal provides one-stop shopping for auto enthusiasts through
up-to-date product information and reviews, how-to advice, community services
and access to products from many leading brands and retailers.  The ACP
enterprise content management capabilities will enable GR8RIDE to easily and
cost effectively redeploy content from Primedia's 29 auto enthusiast magazines
across its portal.  The ACP also will allow GR8RIDE to customize the user
experience throughout the content and retail areas of the site while providing
significant improvements in back-end administration.  With the ACP, many types
of users including editorial, sales, marketing, and supplier and commerce
partners can perform a variety of functions -- from managing content delivery
to administering promotional and advertising campaigns.
    "We are very impressed with Accumedia's functionality and the associated
economic proposition, which we anticipate will reduce our overall Web
operations costs by 55 to 70 percent," said George Vrabeek, CEO of GR8RIDE.
"The managed ACP provides an affordable, high-performance system that gives us
the flexibility to pursue a variety of Web-based revenue and promotional
opportunities.  No other supplier could meet our functional requirements and
still address our aggressive deployment schedule."
    The ACP is a hosted platform that allows Web publishers to focus on their
core competencies -- customers and content -- while Accumedia manages the
complex Web application technology and hosting infrastructure.  The ACP
delivers a complete integration of best-in-breed site design, Web content
management, digital asset management, content relevance and content delivery
capability.  It was developed exclusively to meet the unique needs of
companies who must lower their Web operations costs, while maintaining the
flexibility to easily and quickly modify their online business objectives and
provide the fresh and relevant content that readers demand.
    "Already the premier auto enthusiast portal, GR8RIDE is looking to further
increase its market leadership.  With the Accumedia Convergence Platform, it
will be able to provide a more compelling online experience for its customers
and create a more profitable business for both GR8RIDE and its affiliates,"
said Ed Williams, CEO of Accumedia.  "Our unique Software-on-Demand
functionality will support GR8RIDE's online revenue objectives, while
providing the flexibility to respond to future Web-based opportunities."
    The revised GR8RIDE.com site is expected to launch in August 2001.
