NANDO Media, one of 17 major websites (cumulatively amounting to more than six billion monthly impressions) that have switched from DART or other DoubleClick ad serving technology to 24/7's Open
AdStream in the past year, recently completed an ROI study to see how it was working. NANDO estimates that it has saved $208,375 in the 12 months since migrating to Open AdStream LOCAL. Additionally,
NANDO estimates that it will save $386,413 in year two post migration, and $430,454 in year three, adding up to an estimated saving of more than a million dollars in a three year period as a result of
the switch to Open AdStream LOCAL from DART. This represents an expected 64% reduction in ad serving fees for the three-year period.
