NEW YORK (CBS.MW) -- Consumers will pay $5.8 billion by 2006 for online news, information, audio and video content, and access to entertainment features, according to results of a consumer survey released Monday by Jupiter Media Metrix (JMXI). That's up from an estimated $1.4 billion this year, implying revenue growth compounding at a decidedly optimistic 40 percent a year.

The categories most likely to produce the highest revenues from subscriptions and access fees are audio/video entertainment ($600 million), adult entertainment ($400 million), and investor-related information ($350 million), the researchers said. JMM presented its report at the opening of the research firm's ninth-annual Media Forum, a two-day conference taking place at the New York Hilton
