When Yahoo was looking for a white knight in its fight against Microsoft, Google was offering help, mostly to avoid that Redmond acquired tools developed by Yahoo. After weeks of uncertainties, and considering the legal problems with which Google will have to deal with if bringing its support to Yahoo, Google decided to drop its initial project. So both companies will remain competitors in the online ads market. This is probably not good news for Yahoo considering that the current economic situation will likely to see ads budgets to be decreased.
