The OLAP Report: Consolidated BI: "The BI industry has seen a wave of acquisitions since the mid 1990s, with takeovers occurring every few months. The first wave was mainly other companies who were attracted by the higher growth rates in the BI industry and preferred to buy an existing vendor rather than to develop their own product. These changes of ownership did not produce any consolidation because there was no net reduction in the number of BI vendors or products. There was also no reduction in competition as market shares were not concentrated in fewer and fewer hands. Examples of such non-consolidating acquisitions include the entry of the various database vendors into the BI market, including Oracle's purchase of the Express business from IRI Software, Informix buying STG MetaCube and Microsoft's purchase of the Panorama technology."
