The Reuters Insider service - which can also be accessed through iPhones and BlackBerrys - will provide on-demand multimedia programming, including live coverage of breaking news, interviews, analysis and commentary.

In addition to programmes from its 2800 journalists, the firm has also signed up over 150 partners, including CNBC, Citibank, Nomura and Roubini Global Economics, to provide content.

The company is courting more providers, providing an Insider Desktop studio to help people produce their own videos using nothing more than a webcam.

Unlike cable channels such as CNBC, Bloomberg and the Fox Business Network, Insider lets users create their own channels, applying filters to help them find relevant information based on sectors, markets, regions.

The firm is also using voice recognition technology to provide real-time transcripts of the shows, which viewers can scan before jumping to the relevant part of the programme. If they find something of particular interest, subscribers can then share shows with contacts and customers via e-mail and instant message.

Devin Wenig, CEO, Thomson Reuters Markets, says: "Today's generation of financial professionals access and act on information in a whole new way. Reuters Insider was built to give our clients a competitive advantage and arm them with the multimedia tools needed to work faster and smarter."
