The answer lies on the quality of content presented from the marketer. They might of paid for 30 seconds of advertising however if executed properly they will have left various calls to action that will extend days and maybe weeks after your original commercial was aired.
A great example of this and the best commercial from a marketing standpoint in my opinion was Audi's "Vampire Party" commercial.
In the last few seconds of the ad, Audi displays a black frame with #solongvampires in white standing out to its audience.
This was a unique approach, while others were briefly plugging their Facebook or Twitter accounts, (some weren't doing any) Audi was building a trend. A trend in which was tweeted by 10's of thousands of users with a reach in the millions. Good or bad the brand Audi was being promoted on this trend #solongvampires.
Audi's commercial took traditional marketing and directly engaged it with social marketing something I think others took serious note on and something we will only see more of in the coming years.
