The process by which language is written down or broadcast electronically has often played a great role in creating the standard form.
Before the 1st printing press was in operation in Britain written English varied a great deal from place to place because written English reflected the local dialect of the writer. But when printers had to distribute printed material throughout Britain, some form of standardization was needed. The first printer was located in the Midland region of England (around London) and he used his local dialect (spelling and grammar) as the standard. Eventually other printers adopted the Midland standard as their own.
Today standard English in the U.K. is based on what is taught in Britain's public schools (actually what Americans know as private schools- they are open to anyone in the public who can pay the tuition). It is also known now as BBC English since it is what you hear from BBC anchormen. In America news anchors are taught to use the dialect that you'd hear in the Midwest. It is considered to be the dialect that all Americans can understand even if it is not the dialect that all Americans use in their day-to-day lives.
So it is true that the standard is based on what is in use, but it is not true that what is in use is always standard.
