According to Insight Research's 51 page market report, "Peer-to-Peer & File-Sharing Services Market 2007-2011", P2P could generate up to $28 billion in revenues for telecom carriers and ISPs over the next five years.

The report focuses on Internet infrastructure and technology for IP-based services such as VoIP (Internet phone calls) and HDTV that use P2P architectures. The $28 billion does not cover content or applications,

Robert Rosenberg, President of Insight Research, said "P2P and file-sharing services have moved into the mainstream and are now well beyond the early days when a few of the early service providers ended up in litigation,"

"Peering and file sharing have now been embraced by fixed-line and wireless operators, many of the intellectual property (IP) issues that led to legal fights have been resolved, and media and applications such as ring-tones, games, music, and large-file videos are taking off. We see this market continuing to grow as consumers increasingly rely on the utility of these applications."
