This information also confirms that to market through social media, you can not simply ignore other video media. Some commercials, such as the Lebron/Kobe puppet commercials from Nike have found their way to YouTube. Clever subject matter and coordination of social media tools can help increase consumer awareness of a product and its features.
It is also possible with older media such as television. At times, your audience is online with a laptop while the TV is on. A potential customer can see an TV ad asking the viewer to come to a Facebook Fan Page or website, and go to it immediately on their laptop or even mobile device. The best marketing comes from the best coordinated effort.
