Outsell, Inc. has released a new market sizing study that examines changes in the corporate training and learning market. According to the study, economic pressures combined with changes in technology and human resources practices, have forced leading companies to adjust with new technologies and strategies. Outsell says that every segment in the industry has been experiencing extremes of growth and decline, M&A activity, and moving-target technology. One of seven segment-specific reports in Outsell's annual sizing of the Information Content Industry, the study identifies 499 players in the Corporate Training and Learning segment, their growth rates, and market shares. The total size of the segment in 2001 was $6.3 billion, a 9.8% decline from the previous year. According to Outsell, merger activity was most pronounced among training content providers, the largest of the three segments in the study. The 380 companies in that segment develop and/or deliver training content, and they represent 85% of overall corporate training and learning revenue. The segment includes large firms such as Berlitz, Global Knowledge Network, ExecuTrain, and SmartForce. A string of acquisitions and broken deals among companies such as SmartForce, Centra, SkillSoft, and Books24x7 characterized the activity in the space. The other two types of training and learning companies covered in the study are technology infrastructure vendors and services vendors. Corporate Training and Learning is available for $1,295, including an Industry Overview. Additional industry segments cost $895. The entire series is available for $6,000, which includes all seven segment Briefings and the Industry Overview.
