Aljazeera's program Witness had an item on international remittances last night on UK TV covering services such as Western Union.
Sadly they did not cover the elephant in the room: Bitcoin. But it did delve into corruption within the industry.
A very interesting document, especially when you look at the new 'innovative' services that are being launched in this space.
