"Eric Knorr, executive editor of InfoWorld, first used the term in front of a large audience in the December 2003 special issue of the business IT magazine CIO. Later, as we pointed out in Chapter 1, most people credit Battelle and O'Reilly with coining the term at an O'Reilly Media conference brain–storming session in 2004. There, Dale Dougherty and Craig Cline also used the term, which shortly became notable. Dale Dougherty, Web pioneer and O'Reilly vice president, noted during the conference that 'far from having 'crashed,' the Web was more important than ever, with exciting new applications and sites popping up with surprising regularity.'"
