Mobile Radio Simplified. Accessible. Relevant.

Ten years ago, mobile advertising was in its infancy, something that most cellular users had not encountered. In 2008, an eMarketer study finds that 58 million US mobile subscribers have seen a mobile advertisement on their phones in the past 30 days. That accounts for 23% of U.S. mobile subscribers.

While far from market saturation, it does represent a substantial increase, one that will continue in its upward trend.

But just how lucrative is the mobile advertising market? Ask 10 people and you’ll get 10 different answers. MocoNews this week summed it up by showing that mobile advertising forecasts range anywhere from $11 billion to $250 billion in the next several years.

Compared to the $871 million spent on mobile ads worldwide in 2006 (according to Informa Telecoms & Media), even the most modest projection represents an 1100% increase.

But will mobile users tolerate ads served over their most personal media device? eMarketer goes on to say that for some, the answer is yes.

In addition, 32% of mobile data users said they were open to receiving mobile advertising if it lowers their overall bill and 13% were open to mobile ads if it improved the media and content currently available.

This stat overlooks the more subtle and natural form of mobile advertising, the audio ad. When served in the midst of audio and radio content that consumers deliberately seek out, those numbers may increase. After all, the audio ad overcomes barriers inherent in data based ads, because it is accessible to every phone. It is universally accessible, just like the audio content that is attached to it with cellecasting.

The next few years will see enormous increases in mobile ads. We predict a big portion of that will be in ubiquitous, short, interactive audio ads placed amidst premium talk radio content that is more and more moving to on-demand mobile delivery.
