I recently discovered a company called Video Infusion who specialises in the making of interactive videos - videos that enable viewers to be able to view, click and buy products right from within the video. This type of technology is similar to Youtube's click-to-buy where if you are not familiar users are able to buy songs and movies via Youtube videos using link overlays (links that appear in the video). Currently, as far as I am aware Youtube is only testing this in certain countries and as yet is not available in Australia or New Zealand.
It will be interesting to see this technology evolve as so far Video Infusion seem to be main player offering more then just songs and movies. I feel it will not be long before Youtube too enables the purchase of not just songs but any products. My guess is Google Checkout will somehow be involved.
To give you an idea of how the technology works, have a quick view of the below video, courtesy of Video Infusion.
I would be interested to hear from anyone who has seen this technology used anywhere else.
