The reason I ask is because eMarketer says "Most of their (B2B Marketers') targets—businesspeople—don’t have audio turned on in the office. Talking heads or voiceovers that no one hears are not very effective."

This blog post started out as a question, a plea for answers about communicating with text versus communicating with video. I may make a living off of selling streaming video, but as an avid reader I know video isn't always the best way to communicate your message.
The experiment was simple. They presented the same news story in both text and multimedia (video) to different people and then gave them the same quiz to test what they recalled. Here are their findings:
videos and make it searchable?
including the right text with the video. The obvious next step was finding a way to use speech recognition technology to convert the audio content that is already there to searchable text. The next step after that is making the image content searchable. (Which is well on its way. 
With the seemingly endless buzz around the iPhone, online marketers can't avoid the pressure of pausing and considering how this affects their strategies.
