The meaning and usage of the word "radio" has developed in parallel with developments within the field of communications and can be seen to have three distinct phases: electromagnetic waves and experimentation; wireless communication and technical development; and radio broadcasting and commercialization. Many individuals—inventors, engineers, developers, businessmen - contributed to produce the modern idea of radio and thus the origins and 'invention' are multiple and controversial. Early radio designs could not transmit sound or speech and were called the "wireless telegraph." Development from a laboratory demonstration to a commercial entity spanned several decades and required the efforts of many practitioners. In 1878, David E. Hughes noticed that sparks could be heard in a telephone receiver when experimenting with his carbon microphone. He developed this carbon-based detector further and eventually could detect signals over a few hundred yards. He demonstrated his discovery to the Royal Society in 1880, but was told it was merely induction, and therefore abandoned further research.

Hi there, the very beginning of this story reads: "It was Lady Windermere’s last reception before Easter, and Bentinck House was even more crowded than usual. Six Cabinet Ministers had come on from the Speaker’s Levée in their stars and ribands..." Now, I would like to know what that Speaker's Levée exactly is, though I guess the Speaker is the presiding officer of the House of Commons and that Levée some kind of political ceremony... Do you have any more precise idea? Thanks
