"The cost of getting every UK home onto fibre-optic super-fast broadband could be close to £30 billion according to the government's broadband advisory group.

With increasing numbers of Britain's population now looking to receive much faster connections, the government's Broadband Stakeholder Group has put the cost of rolling out fibre-optic cable across the country at between £5.1 billion and a staggering £28.8 billion depending on what technology is used"

 

Looks like digital downloads could be years away in the Uk atleast , and if develoepd countries like the UK would struggle to go fibre optic what about developing countries ? Digital Downloads might not be global for another 5-15 years depending on the countries growth.
