The number of subscribers using mobile Internet services will rise from 577 million currently, to top 1.7 billion by 2013, spurred by demand for collaborative applications known collectively as Web 2.0, and greater 2.5/3G penetration. Established mobile players face increasing competition from web-based brands and will have to adapt their commercial strategies to accommodate greater collaboration with other members of the value chain, if future revenue growth in the mobile Web 2.0 space is to be achieved. "Major web players have already crossed the Rubicon and established themselves in the mobile domain, placing the onus on MNOs and other members of the value chain to form innovative relationships and grab a share of the new revenue streams being created," comments Ian Chard, of Juniper. "The mobile Web 2.0 market is still nascent and business models remain in a state of flux, so there is still time for players to establish fruitful partnerships that build on their strengths and are reciprocally beneficial. The window of opportunity, however, is closing." Article
