Microsoft friendly bid for Yahoo turns hostile

Following the announcement of the board of Yahoo to refuse the offer from Microsoft to purchase it, Microsoft have increased the pressure and has addressed shareholders directly in an attempt to convince them of the commercial merits of their offer.
It appears that MS is now moving towards a hostile takeover of the coveted company. This solution may cost them much more than 44 billion, since other interested parties, such as Google, could raise the stakes in the rush to gain control.
