The Market News Support Branch (MNSB) is responsible for administering and maintaining the Market News Information System (MNIS), the Market News Communication System (MNCS), and the Market News Web site as well as associated Internet delivery systems. The MNSB provides service to all six AMS commodity program market news operations, and is the central point of coordination and support for the automated systems that are vital to the success of the market news program.

The MNSB is composed of two information technology groups; market news information systems (MNIS) and market news communication systems (MNCS). The MNSB provides information technology support / technical support to AMS market news (Cotton, Dairy, Poultry, Fruit and Vegetable, Livestock and Seed, and Tobacco).

In addition to technical support, the MNSB develops database systems and applications to support the collection of data and information as well as the creation and distribution of market news reports. The MNIS group is primarily application support and development, while the MNCS group primarily supports infrastructure (hardware, severs, operating systems, security).
