Outsell, Inc. has released a market sizing study of the Scientific, Technical, and Medical (STM) segment of the Information Content (IC), examining changes in 2001, the current state of the market, and prospects for the future. Outsell found that revenues for the 237 companies in the $9.3 billion STM segment of the IC declined by 0.8% in 2001. Much of the decline can be attributed to overall economic conditions, according to Outsell, but prospects for the future are solid for the STM content that plays a large role in the development of new products. The top three overall players in this segment, Elsevier Science, Wolters Kluwer, and Thomson Scientific & Healthcare, grew by 32.6, 8.3, and 6.7%, respectively. The top 10 STM publishers' revenues were up a total of 15.4%. Outsell's report analyzes the size, growth rates, and market shares of 237 STM content companies. With data from the Outsell 60 Company Monitor and Outsell's proprietary information about end user information habits and preferences, the study aims to provide a comprehensive picture of the STM content marketplace.
