News is coming in from the States that Apple is about to enter the mobile ad market with the purchase of ad network Quattro Wireless for approx. $250 million. This will be Apple’s first move into adland as it broadens its mobile experience by offering its app developers the opportunity to also make money from advertising.

The move follows hot on the heels of Google’s acquisition of mobile network AdMob. Marketers and publishers can now be in no doubt that the future of advertising is mobile, whether it be on the iPhone, the Nexus One, other smart phones or of course the fabled Tablet computer (now being called the iSlate).

With Google busying itself developing apps for the Nexus One and Apple having the lion’s share of app-land already, this may be the conclusion of the app wars and what we are now seeing is the start of the mobile advertising wars between the two giants of mobile media and marketing.
