"If a picture is worth a 1000 words, then a video is worth a 1000 words, 25 times a second."
Video is the integration of three separate aesthetic concepts: visual, sound and concept. Combining three art forms to create video allows viewers the chance to a unique experience. This model is why film is one of the dominant art forms of the 20th century.
How does this relate to the internet and video marketing? More people are using the internet for entertainment and business. The world's population is at 7 billion people. Over 2 billion of those have internet connection and more than 5 billion have mobile phone access.
If these figures say anything it's that video marketing unlocks opportunities for businesses at the low price of 'free'.
