As you may be aware of earlier today, Yahoo and Microsoft announced a 10 year partnership, to hopefully challenge Google's dominant 55% share of the search engine market.
This means that Microsoft will be in full command of all search engine facilities, with Yahoo taking contol all Microsoft marketing.
They will create an immediate 30% share of the market.
Allthough user's won't notice a difference, this means the end of Yahoo as a search engine.
