A boycott is normally considered a one-time affair designed to correct an outstanding single wrong. When extended for a long period of time, or as part of an overall program of awareness-raising or reforms to laws or regimes, a boycott is part of moral purchasing, and those economic or political terms are to be preferred.
Most organized consumer boycotts today are focused on long-term change of buying habits, and so fit into part of a larger political program, with many techniques that require a longer structural commitment, e.g. reform to commodity markets, or government commitment to moral purchasing, e.g. the longstanding boycott of South African businesses to protest apartheid already alluded to. These stretch the meaning of a "boycott."
Boycotts are now much easier to successfully initiate due to the Internet. Examples include the gay and lesbian boycott of advertisers of the "Dr. Laura" talk show, gun owners' similar boycott of advertisers of Rosie O'Donnell's talk show and (later) magazine, and gun owners' boycott of Smith & Wesson following that company's March 2000 settlement with the Clinton administration. They may be initiated very easily using either Web sites (the Dr. Laura boycott), newsgroups (the Rosie O'Donnell boycotts), or even mailing lists. Internet-initiated boycotts "snowball" very quickly compared to other forms of organization.
Discussion
Boycotts are unquestionably legal under the common law. The right to engage in commerce, social intercourse, and friendship implies the right not to engage in commerce, social intercourse, and friendship; since a boycott is voluntary and nonviolent, it is unable to be stopped by the law. Opponents of boycotts historically have the choice of suffering under it, yielding to its demands, or attempting to suppress it through extralegal means, such as force and coercion(Kelley, 2001, pp.25-30).
Boycotts are generally legal in developed countries. Occasionally, some restrictions may apply; for instance, in the United States, it may be unlawful for a union to engage in "secondary boycotts" (to request that its members boycott companies that supply items to an organization already under a boycott, in the United States); however, the union is of course free to use its right to speak freely to inform its members of the fact that suppliers of a company are breaking a boycott; its members then may take whatever action they deem appropriate, in consideration of that fact. Individual consumers are always free to make whatever purchasing decisions they want, for whatever reasons they wish; that is the essence of a free society and a free market.
As confusing and diverse as consumer boycotts-and the organizations that instigate them-- have become, three conclusions can be drawn with some certainty from the history of boycotts over the past decade. First, the root causes are increasingly social or political rather than the traditional economic issues of high prices or even labor union representation(Vogel, 1998, pp.56-70). Second, more and more often the apparent target of a boycott is not the "real" target--that is, not the organization the boycotters are really trying to affect or influence, ...
