Marketing, sales, and customer service departments -- not IT departments -- are viewed as innovation engines in corporate executive suites, according to a survey released today by The Economist's Intelligence Unit.

That means merging some of the central activities of the CMO and CIO.” Only 17% of C-level executives queried in the poll said IT helped bring innovative ideas to market. Marketing, however, was named by 47%.
