By engaging hitherto reluctant viewers to get their daily dose of programmes online, the BBC has created an unprecedented demand for online capacity, something that has caused broadband providers to struggle to deliver optimum quality of service.
Times Online mentions that David Attenborough’s Life in Cold Blood gobbles up to 600MB worth of download capacity per hour and given that too many entry level broadband packages have monthly download limits of 1GB, this could be the perfect recipe for disaster and could see a number of people using their monthly quota in a couple of hours.
What's more, many of those online viewing technologies - like the iPlayer uses Peer to peer technology - which consumes both your download and upload quota; something that many users are not aware of.
The Times Article also revealed that even trivial Internet tasks like changing your Facebook page or your Myspace profile can consume up to 400MB per hour; and with both popular social networking sites bound to announce free ad-supported streaming music in the near future, this could send millions of new users online.
