Microsoft had a $100 Million ad budget for Bing and its spending every penny to promote it quite successfully. Recently Microsoft has pushed out another ad and this time its directed at Bing’s Cashback and as we all know it will save us cash while we make purchases online using Bing search. I was highly critical when Microsoft earlier launched its Cashback program earlier and thought of it to be the most desperate move to make users use its search. But I guess I will have to change that stance, given that Bing is already faring well.
