Pierre Noizat from Bitcoin.org discusses the growth of the online peer-to-peer currency and we discuss how digital technologies are changing the commercial image library business

This week on Tech Weekly with Aleks Krotoski, we meet the CEO and founder of Shutterstock.com Jon Oringer. Jon talks to Guardian technology editor Charles Arthur about his data-driven twist on the photo-library business and why cheap high-quality cameras are allowing both photographers and commercial customers to do business in a very different way.

Aleks and Charles discuss the impending Christmas battle of the tablets and why a small town Australian police force is furious with Apple maps. And Pierre Noizat from Bitcoin.org discusses its peer-to-peer currency.
