Staatsbedrijf der Posterijen, Telegrafie en Telefonie

From 1928 to 1989, Staatsbedrijf der Posterijen, Telegrafie en Telefonie (PTT) 1 was the Dutch state-owned telecom monopolist, responsible for mail, telegraph and telephone services. It was the successor to the P&T, and was part of the Ministry of Transport (Dutch: Ministerie van Verkeer en Waterstaat). In 1989 privatised and split into Postbank (bank), TPG (mail) and KPN (telecom).

In the period following WWII, the Dr. Neher Lab of the PTT — at the time considered the Dutch national research laboratory — developed a series of cipher machines at the request of the Dutch Government. The production and development of these machines was later taken over by Philips Usfa. Until 1989, the Radio Monitoring Service (RCD) 2 was part of the PTT, and was responsible for enforcement of the telecom laws, in particular with respect to the use of the radio spectrum.

The Dutch PTT was formed as an independent organisation in 1893, by merging the postal services (Posterijen) and the telegraph service (Rijkstelegraaf), under the name Administratie der Posterijen & Telegrafie (APT) — the Post & Telegraph Administration [1]. In 1897 the former Rijkstelegraaf acquired the long distance call network of the Nederlandsche Bell-Telephoon Maatschappij (NBTM) – at the time the largest telephone service provider in the Netherlands.

In 1915, after the introduction of the Business Law 1912, APT was renamed Staatsbedrijf der Posterijen en Telegrafie (P&T) — the state-owned company for Post and Telegraph. To include the telephone service in its name as well, P&T was renamed in 1928 Staatsbedrijf der Posterijen, Telegrafie en Telefonie (PTT) — the state-owned company for Post, Telegraph and Telephone.

During WWII, PTT was privitised by the German occupant, which was undone immediately after the war had ended in 1945. This situation lasted until the late 1980s, when the PTT was officially privatised and split into three organisations for bank, post and telecommunications respectively.

The bank service was the first to be split off in 1986 as Postbank. It had been formed in 1977 by merging the Rijkspostspaarbank (RPS) and the Postcheque & Girodienst (PCGD). The Postbank was merged in 1989 with the NMB bank into the NMB Postbank Group, and in 1991 with Nationale-Nederlanden (NN) into the Internationale Nederlanden Group (ING), with Postbank and ING Bank as separate services and brands. In 2009, Postbank and ING Bank merged their activities into ING.

The rest of the former PTT was privatised in 1989 as Koninklijke PTT Nederland NV (KPN) — the Royal Dutch PTT — which comprised two services: PTT Post BV and PTT Telecom BV. Until KPN went public in 1994, the Dutch state was the only shareholder. In 1996, KPN acquired TNT and merged it with PTT Post into the TNT Post Group (TPG). The postal services were renamed TPG Post in 2002. In 1998 KPN was split into separate companies for post and telecom.

The post went on as TNT Post Groep NV (TPG), with Koninklijke PTT Post and TNT as daughters. In 2005, TNT Post Group NV (TPG) was renamed TNT NV, and in 2006, TPG Post was renamed Koninklijke TNT Post BV (TNT Post). The TNT part was split-off in 2011 as TNT Express, which was taken over by FedEx in 2016. The postal service was renamed Koninklijke PostNL in 2011.

The former PTT Telecom branch went on as Koninklijke KPN NV (KPN), and specialised as a tele­communications, internet and television service provider. Until 2005, the Dutch state was one of the largest shareholders, but in 2006 the last 8% of the shares were sold [1].
