Tamara Barber of Forrester Research defines and discusses market research online communities (MROCs). MROCs are captive interactive online groups joined by common interest that are systematically used for market research over time. Various terms are used for MROCs, including idea spaces, online insight villages, and communities. MROCs are evolving to be more mobile and social and engage businesses earlier in the planning process. Regardless of the term used, MROCs will continue to change in strategic ways.
