Citizens Band Radio
Citizens' Band radio (also known as CB radio) is, in many countries, a system of short-distance radio communications between individuals on a selection of 40 channels within the 27-MHz (11 m) band. Citizens' Band is distinct from the FRS, GMRS, MURS and amateur ("ham") radio. In many countries, CB operation does not require a license, and (unlike amateur radio) it may be used for business or personal communications. Like many other two-way radio services, Citizens' Band channels are shared by many users. Only one station may transmit at a time; other stations must listen and wait for the shared channel to be available.
A number of countries have created similar radio services, with varying technical standards and requirements for licensing. While they may be known by other names, such as the General Radio Service in Canada, they often use similar frequencies (26 to 28 MHz), have similar uses, and similar technical standards. Although licenses may be required, eligibility is generally simple. Some countries also have personal radio services in the UHF band, such as the European PMR446 and the Australian UHF CB.

We bring the numbers down—not by solving the problem, but by deciding it’s their own damn fault.”
—Anna Quindlen (b. 1952)

And Sir Gerald again
And the band of the Waldorf-Astoria.”
