The market for fixed line telephony services and infrastructure was monopolized by the state until 1990. The state monopoly was implemented by the PPTiT which was subordinated to the Ministry of Communications. The telephony segments of that entity were spun-off and incorporated into Telekomunikacja Polska which was later privatized and sold to Orange Polska. The Telecommunications Act of 1990 allowed the provision of telecommunication infrastructure and services by the former monopoly. After 2000, other operators were allowed to use TP's telecommunications infrastructure under Third-party Access.
