Telegroup was a telecommunications company founded in 1985 that provided international long-distance calling services. The company was headquartered in Fairfield, New Jersey, and operated as a reseller of international telecommunications services. During its peak in the 1990s, Telegroup served customers in multiple countries across North America, Europe, and Asia. The company specialized in offering callback services and international calling cards, which allowed customers to make international calls at reduced rates compared to traditional carriers. Telegroup’s business model capitalized on arbitrage opportunities in international telecommunications pricing, particularly during the era before widespread deregulation of telecommunications markets. In 1998, Telegroup went public through an initial public offering (IPO) on the NASDAQ stock exchange. However, the company faced significant challenges due to increasing competition, regulatory changes, and the emergence of new telecommunications technologies. In 1999, Telegroup filed for Chapter 11 bankruptcy protection and subsequently ceased operations. The assets of Telegroup were eventually acquired by other telecommunications companies, marking the end of its independent operations. The company’s rise and fall reflected the volatile nature of the telecommunications industry during the 1990s, as traditional long-distance service providers faced disruption from new technologies and business models.
