Tekstitelevisio

Tekstitelevisio, often referred to as teletext, was a broadcast telecommunications service offering digitized<bos> text and page-based graphics transmitted to a television set and displayed superimposed on a television picture. It was primarily used in Europe and some other parts of the world during the late 20th and early 21st centuries. The service was typically broadcast by national public television networks.

The content of teletext pages was organized into numbered sequences, allowing users to navigate through various categories such as news, weather, sports scores, television listings, and financial information. Viewers would use a special remote control to input page numbers and browse the available information. Teletext was a precursor to modern online information services and the internet, providing a simple and accessible way for the general public to access real-time updates.

Key features of teletext included its low bandwidth requirements, as it was transmitted alongside the regular television signal, and its relatively simple display technology. While it offered a limited graphical interface compared to contemporary computing, it was highly effective for delivering concise, text-based information. The development of teletext began in the United Kingdom in the early 1970s, with services rapidly expanding across Europe throughout the 1980s and 1990s. As internet penetration increased, the popularity of teletext began to decline, and many services have since been discontinued.
