The beginning of regular commercially licensed sound broadcasting in the United States in 1920 ended the print monopoly over the media and opened the doors to the more immediate and pervasive electronic media. By 1928, the United States had three national radio networks - two owned by NBC (the National Broadcasting Company), and one by CBS (the Columbia Broadcasting System). Until 1943, there were four major national radio networks: two owned by NBC, one owned by CBS, and one owned by Mutual Broadcasting System. The NBC's second network became ABC, the American Broadcasting Company.

Though mostly listened to for entertainment, radio's instant, on-the-spot reports of dramatic events drew huge audiences throughout the Great Depression of the 1930s and World War II. President Franklin D. Roosevelt recognized the potential of radio to reach the American public, and during his four terms (1933-1945), his radio "fireside chats" informed the nation on the progress of policies to counter the Depression and on developments during World War II.

After World War II, television's visual images replaced the audio-only limitation of radio as the predominant entertainment and news vehicle. Radio adapted to the new situation by replacing entertainmentprograms with schedules of music interspersed with news and features, a freeform format adopted by NBC when it launched its popular weekend-long Monitor in 1955. During the 1950s, automobile manufacturers began offering car radios as standard accessories, and radio received a big boost as Americans tuned in their car radios as they drove to and from work.

The expansion and dominance of FM radio, which has better sound quality but a more limited range than traditional AM, represented the major technical change in radio in the 1970s and 1980s. FM radio, aided by the invention of ever smaller portable radios and inexpensive "Walkman" headsets, dominates music programs, while AM has shifted to "talk" and news formats. Barely in existence 25 years ago, "talk radio," in which celebrities and experts from various fields answer listener "call-in" questions and offer their advice on various topics, has grown spectacularly in recent years. It has contributed to the comeback of AM radio. Both FM and AM radio have become increasingly specialized. Music formats, for instance, comprise a variety of specializations -- the top five in 1991 being "country and western," "adult contemporary," "top 40," "religious" and "oldies.

A hotel is an establishment that provides paid lodging, usually on a short-term basis. Hotels often provide a number of additional guest services such as a restaurant, a swimming pool or childcare. Some hotels have conference services and meeting rooms and encourage groups to hold conventions and meetings at their location.
