Other examples of pre-modern long-distance communication included audio messages such as coded drumbeats, lung-blown horns, and loud whistles. 20th- and 21st-century technologies for long-distance communication usually involve electrical and electromagnetic technologies, such as telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, and communications satellites. A revolution in wireless communication began in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi, who won the Nobel Prize in Physics in
Radio Marconi “Most InAVative Leisure & Entertainment Facility” category at the InAVation Awards 2013, for the interactive multimedia seatback system integrated into the Royal Opera House in Muscat. The company is known mainly for its surtitle and supertitle systems, as well as the electronic libretto, seat back titles, and libretto translation technology.
