Why are text messages, phone calls and other data sent via the telephone billed based on the frequency of use while if the internet is used to transmit the same data, an unlimited amount of data can be uploaded and the user is billed a very cheap fixed rate? An example of this is Sky Internet in the UK. The maximum speed for their basic service is a very high 5Mbits/s (640KB/s), where a high definition video conference call can be sustained without buffering time lags, unlimited downloads can be made, and a compressed 700MB, 2 hour, DVD quality movie can be downloaded in only 18 mins., and despite all of these very sophisticated features, the bill amounts to only 10 pounds per month. While the fiber optic internet service at 40Mbits/s (5.12MB/s), where the same 700MB movie can be downloaded in only 2.3 mins., only costs 32.5 pounds per month.
