3D technology developer DDD will arrive on Aim on 3 January having raised £7m through an Old Mutual-advised placing of 10,769,231 shares at 65p. DDD (or Dynamic Digital Depth) develops technology that enables producers of 2D media to convert their content to a 3D format. This can be then viewed through TVs and computer monitors adapted by software and hardware also designed and developed by the company. The technology's major selling point is that the 3D effect can be achieved without viewers having to wear 3D glasses. According to DDD's management in the past the need for glasses has been 'the principal obstacle to mass commercial acceptance of 3D'. With this now overcome they suggest that 'the impact of 3D TV will be as significant as the transition from black and white to colour television'. Interest in DDD's 'OpticBoom' technology has come from a broad spectrum of areas including Korean electronics group Samsung, Japanese IMAX postproduction house IMAGICA and German precision optics manufacturer Zeiss. The decision to list on London's junior market reflects the next stage of DDD's development. Until now the company has focused heavily on research - in the nine months to September revenue of only £131,000 was generated as losses topped £2.45m - it is now looking to increase sales and marketing expenditure and appoint a network of resellers.
