July 29, 1998, was a turning point for Brazil’s telecommunications sector. On that date, the federal government privatized the Telebrás System through 12 consecutive auctions at the Rio de Janeiro Stock Exchange. The transactions transferred controlling stakes in the companies that had made up the state-controlled operating system, ending federal control of those operators.

The sale followed a wider legal and regulatory overhaul. Brazil’s General Telecommunications Law, Law No. 9,472, had been enacted on July 16, 1997. The law created the National Telecommunications Agency, known as Anatel, and set out rules for private-regime services, non-exclusive concessions and safeguards intended to promote free, broad and fair competition.

What happened

According to the Brazilian Development Bank, BNDES, the Telebrás System was reorganized into 12 companies before the sale. They consisted of three fixed-line holdings, one long-distance company and eight cellular holdings.

All 12 were sold in auctions held on the same day. BNDES records proceeds of approximately R$22 billion, with bids representing a 63% premium over the minimum price. Contemporary reporting by Folha de S.Paulo put the total at R$22.058 billion and the average premium at 63.74%.

The transactions did not stand alone as an ownership change. They took place within the framework established by the 1997 law, which created Anatel as the sector regulator and provided for a telecommunications market in which concessions would not necessarily be exclusive.

Why it matters

The privatization is significant because it combined two changes: the transfer of control over the former Telebrás operating companies and the establishment of a new regulatory structure for the sector. Rather than treating the auction as a single isolated event, the record shows a sequence in which legislation created the framework and the 1998 auctions changed the ownership of the operating system.

For an international audience, the episode remains an important example of how Brazil restructured a major network industry during the 1990s. The law’s provisions on private-regime services, non-exclusive concessions and competition safeguards set the terms of the post-Telebrás system, while Anatel became the public authority responsible for telecommunications regulation.

By the numbers

The bigger picture

Anatel’s figures point to a substantial expansion in the number of telecom accesses over the following two decades. Its comparison covers fixed telephony, mobile telephony, pay television and fixed broadband: categories that reflect both the growth of communications networks and the emergence or expansion of services beyond the fixed-line market.

That expansion should not, however, be presented as proof that privatization alone produced the result. Anatel identified substantial infrastructure investment after 1998, while also pointing to previously suppressed demand and the arrival of new services as relevant factors. The available evidence documents the regulatory and ownership changes, as well as the later growth in combined accesses, but does not isolate privatization as the single cause of investment or access growth.

The distinction matters because the 28 million-to-roughly-325 million comparison is not a measure of competition alone. It combines different technologies and services, including mobile communications, pay TV and fixed broadband. It is therefore best read as an indicator of the broader scale of telecommunications access, rather than as a standalone verdict on any one policy change.

What happened next

After the 1998 auctions, Brazil’s telecommunications sector operated under the framework introduced by the General Telecommunications Law and overseen by Anatel. Twenty years later, Anatel’s July 2018 projection suggested that combined accesses across the four cited service categories would reach about 325 million by the end of that month.

The July 29, 1998 sale still matters because it marks the moment when Brazil’s former state telecom operating system moved into private control under a newly established regulatory regime. The scale of subsequent access growth is documented, even if the evidence does not support assigning that change to privatization alone.
