Based on the latest IDC report on tech marketing spend, not a lot. In fact, social media doesn’t seem to even register as a discrete item on the tech marketing agenda. It is possible that social media is lumped in as part of “other” digital marketing (which constitutes less than 1pc of total marketing spend). Which seems to bear out that in spite of all the talk and promise surrounding social media, it hasn’t yet made a significant impact on tech vendor marketing spend. It will be interesting to see what happens over the next 12 months in terms of social media’s share of marketing wallet. Or will a tough economy see vendor marketers retrench into sticking with traditional marketing tactics? eg events.
