Google acquired AdMob, silicon valley based startup for a price of $750 Million. This startup was focused on mobile advertising specifically for the growing smartphones, iPods, iPhones, Androids and so on.

Apple is also not behind in the race. Recently there was a cold war between Apple and Google over Google Voice application denial and also the most famous story of 2009, Eric Schimdt, who is Google’s CEO, resigning from Apple as board of director.

Apple is also rumored to be making a new map application which would challenge it’s rival Google Maps , currently used on all iPhones. Apple has challenged Google in nearly all fields and this step could be another challenge.

Quattro Wireless is also another startup which concentrates on advertising on Smartphones. It is supposed to be acquired for a price of $275 Million and the news is expected to arrive today.
