If you had asked me a few years ago, I would have said Thomson was making a play for virtual control of this market. Now they're out, dumping Thomson Learning for $7.75 billion. What's changed? Tony Karrer offers some links to some discussions looking at, say, content vendor value. It may be that between the free software and the open content and the learning communities there just wasn't a large enough market to control. Anyhow, I think this is big news, because there is no obvious company poised to step in where Thomson is leaving off. Meanwhile, as Jay Cross reports, "Reuters agreed this morning to a takeover by Thomson for $17 billion. Reuters CEO Tom Glocer will lead the new company, Thomson-Reuters, which will be larger than Bloomberg in the financial data marketplace."
