Radio Broadcasting

The broadcasting industry is the oldest form of electronic communication. In the early 20th century, radio was a purely experimental medium, where innovators struggled in ways to transmit Morse code through new wireless technology. Over time, transferring points and scripts will give way to voice and music transfer. By the end of the 20th century, radio had become a multi-billion dollar information and entertainment industry used by people around the world.

Radio is a business that connects advertisers and audiences that are attracted to a variety of programming formats. The radio has the ability to attract different demographic groups by programming it, making it an ideal way for advertisers to signal different messages. Music is dominated by music in the FM band (frequency modulation) and conversation and information in the AM band (amplitude modulation).
The radio industry consists of two distinct markets: the local market and the national market. Most listeners learn about the local radio program market, which consists of those stations licensed for a specific geographical area. The local market has a mix of AM and FM stations. The largest markets, such as New York, Los Angeles and Chicago, have more than sixty to seventy licensed stations. Smaller markets can only have three or four seasons.

Wireless interconnecting in USA

Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.
