You might have heard rumors about Google moving into the mobile phone business. Why would Google want to manufacture a phone? Many are speculating the company is diving into this arena to ensure its piece of the mobile internet advertising sector—a new advertising frontier that is expected to grow in the coming years.

This got us thinking about advertising platforms. As we move into the next decade it’s interesting to think about the many new ways advertising will be delivered, from the small screens of mobile phones to digital displays that are larger than life. Industry experts are looking to the new frontiers of personalized advertising and the growth of more eco-friendly platforms like the out-of-home displays from A2aMEDIA that use one-fifth of the energy of traditional signs.

But digital signage is sure to be one of the future’s fastest growing advertising sectors. At A2aMEDIA we see increased interactivity and integration driving segment growth as integration with consumer mobile devices increases consumer engagement. Digital displays will also become more common, placed in a variety of unique venues like offices, sports arenas and public facilities, allowing advertisers to reach just about any target audience they choose.

Simply put, the coming decade will see lots of big changes in advertising mediums and digital display—many that we might not yet be able to even imagine.

You might have heard about the Yas Hotel recently—the building, located in Abu Dhabi, is now home to the largest LED display in the world. Designed to resemble a fisherman’s net, it features multi-colored lights and can even play video clips. Launched on November 3, 2009, the hotel’s display has around 5,000 LED items on 5,300 diamond-shaped steel panels. The Yas itself is made up of two 12 story buildings, which sit on top of a Formula-1 race track.

 There’s no doubt that all of this is pretty spectacular. Still, the Yas installation will most likely be the world’s largest LED display only momentarily.

The digital display industry is moving forward at a break neck speed—many of the world’s past largest displays were installed fairly recently. The GreenPix Zero Energy Media Wall was installed in 2008 for Beijing’s Summer Olympics when it boasted the title of ”The World’s Largest Color LED Display.” Now, less than two years later, the world has a bigger and brighter contender.

Simply put, more spectacular displays are inevitably on the way. Where? We’d love to see one on the Golden Gate Bridge, but that’s just our opinion.

Many different sources, including The New York Times, have reported that Americans are exposed to nearly 5,000 advertisements every day. Hearing figures like that, we can’t help but wonder how any advertiser can hope to break through the clutter to persuade customers to actually buy something.

Recent research from Capital Networks Limited provided one answer: digital signage. According to their research, the digital signage industry continues to forge ahead precisely because the medium is able to grab consumers’ attention. However, in this economy we believe its not just about using the right tools; it’s about how to use them efficiently.

There are lots of ways to improve your use of digital signage, such as message rotation and including a powerful call to action — always. Of course the best “tip” is to keep the message brief — around eight seconds is optimal.
