Mobile Advertising Revenue Models
Forecasts suggest the mobile ad market will generate revenue of $1 billion to $24 billion within the next 4 years, with mobile operators increasingly seeing advertising as a powerful offering, given falling traditional voice revenue, as it allows brands to target consumers based on their location and at times of the day when they are otherwise hard to reach.
While no one debates the potential, executives are pretty clear that any breakthrough is years away and major operators must work together to succeed.
In the meantime, while no one really knows what will work, there is no dearth of revenue models:
Blyk, has signed 100,000 clients in the UK with its offer of some free calls and text messages in return for accepting ads.
Virgin Mobile USA plans to use AOL’s mobile advertising system exclusively to deliver banner ads to its customers who surf the Web on their phones.
First Hop, Finland-based mobile service control company, has a mobile advertising solution that allows operators to offer customers free content or free text or minutes in exchange for receiving advertisements.
Closer home, mGinger and its clones pay users for receiving advertisements on their phones

The main catch is the ads should be content specific, customized for a better user experience. Plus user profiling is also required to support recommendations as with amazon which adds much value for the advertiser.
