Video was it, is still it and always will be it. From the the first time a kid sat in front of a screen and the movement and sound caught their eye, they were hooked. It doesn't matter how it gets delivered, cable, DVD, download, or stream the viewer is insatiable.
I liked this article in MediaPost, it presents interesting facts surrounding use of video.
MediaPost Publications Video is Evolving -- Don't Get Left Behind 11/15/2011:
It is critical to recognize that just putting a video on a web site or in a blog is not good enough any more. With so much to choose from and limited time (even with mobile devices now giving us even more access), the viewer wants to be compelled. Audiences expect more and we can give it to them. We all have something to say, the key is to not suck while saying it. Become your own broadcast media company. Put up your own broadcast antenna so to speak. Make your point relevant, honest and poignant. Your audience will find you.
