Over at the NMA Will 'the Search' Cooper points out that Microsoft has seen its value drop by nearly $40bn (£20.9bn ) since it began its Yahoo bid.
At the same time we're hearing that Microsoft will raise the bid if needs be. So, already, we're looking at the deal costing Microsoft over $40bn and loosing them nearly the same amount again. Hmm. $80bn. You could buy a lot of AdWords with that!
I would not be surprised if the overall tally comes to nearly $100bn before the economies of the deal start to come true.
Update: That's $100,000,000,000.00
