array of telecommunications services from ravi teja's blog

These changes have yielded many benefits, including a much broader array of telecommunications services, a more diversified and competitive market, and an environment in which new innovations move more quickly to the marketplace. But they have also led to decreased industry support for long-term telecommunications research and a general shift in research focus from the long term to the short term. As has been observed by many others, there has been an overall downturn in many areas of U.S. industry research.1 Along similar lines, a report released earlier this year by the National Academies concluded that the nation’s commitment to basic research in science and engineering needs to be sustained and strengthened.

The Bell System ended in 1983. Divestiture resulted in the separation of the local Bell System operating companies (which provided local telephone service to large regions of the United States) from the long-distance parts of the network (known as long-lines communications) and ended the license fee arrangement through which the regional operating companies supported Bell Labs. At the time of the separation, Western Electric (the equipment manufacturing part of the Bell System) was assigned to the part of the company that would be called AT&T), along with most of the research and development resources of Bell Labs. The regional Bell operating companies (RBOCs), the providers of local phone service, formed an R&D consortium called Bellcore (Bell Communications Research, later renamed Telcordia Technologies) and agreed to fund Bellcore to do the majority of the R&D needed to support them— at least for an initial period on the order of 5 to 7 years. Subsequently the RBOCs sold Bellcore to SAIC, causing the new lab to seek support outside the RBOCs and subsequently make radical changes in the scope and direction of its research program.


As a result of divestiture, the fundamental split in the Bell System propelled AT&T (and its R&D arm Bell Labs) into a competitive landscape for the first time, with aggressive competitors such as MCI and Sprint seeking to compete for long-distance services—for both residential and business customers. Thus although a tax on telecommunications revenue remained as a source for funding R&D at Bell Labs, the prospects for increased competition, lower telecommunications prices, and decreasing telecommunications revenues for AT&T, as well as the regulatory pressures to lose market share to new competitors, led to the beginning of the reduction in the long-term, unfettered, fundamental research done at Bell Labs.
