We are all aware of the power of online video in terms of entertainment...from music videos, to adverts to film and TV programmes, but what about harnessing the power of online video for humanitarian and educational benefits?

Today we picked up on the story of 29 year old American woman, Sloan Churman who after being deaf since birth, finally heard her own voice for the first time thanks to a revolutionary new ear implant. The resulting video, captured by her husband, was uploaded to YouTube last week and has since received over 4.25 million views.

The sheer joy and happiness which Miss Churman experiences in the video is infectious and powerful and highlights yet another way in which online video can be used to convey the most basic of things- human emotion.

It is certaintly refreshing to see people utilising video in new and interesting ways beyond basic entertainment. Only last week, we reported on the use of YouTube by a gay American soldier to come out to his parents and this week, Sloan Churman's video definitely struck a chord with us.

So what other ways can online video be utilised for basic human good?

From a social and educational perspective, online video and in particular, taggable video has incredible potential in terms of influence and scope. We already know that static, one dimensional videos shared through YouTube and other platforms can be hugely popular so surely the next logical step is to add dynamic, interactive content which can educate, inform and ultimately improve peoples lives.

From governmental social awareness strategies like anti-smoking and healthy eating campaigns to charity initiatives and children's education - all could benefit from clickable, interactive video.

For example, a healthy eating promotional video could be turned from something which is entirely one-dimensional to something which allows viewers to click on tags and receive built-in information - without having to spend more time searching around the web.

Charities like Oxfam could also benefit from taggable video by giving viewers as much information as possible and adding social media apps to share thoughts, contribute and even donate with one click, all within the one video. The latter will also allow for donations to be made wherever the video is shared or embedded, rather than only from the charity's website.

The opportunities which taggable video presents to government initiatives and charities could be completely revolutionary. With traditional top-down advertising methods becoming less and less effective, providing less results per dollar spend, the time is now to turn towards taggable video.

Indeed, there are currently very few other tools which allow you to maintain a captive audience, push your message, encourage debate, raise awareness and interact with other like-minded individuals all within the one shareable video experience.
