From the BBC:

Consumer demand for bandwidth could see the internet running out of capacity as early as 2010, a new study warns.

US analyst firm Nemertes Research predicted a drastic slowdown as the network struggles to cope with the amount of data being carried on it.

Such gridlock would drastically affect how people use the web and could mean the next Google or YouTube simply doesn't get off the ground, it said.

The report said billions needed to be spent upgrading broadband networks.

It put the figure at around $137bn (£66bn) globally.

For users, the slowdown could see a return to the bad old days of dial-up, the report predicts.
