Televize

Televize, or television, is a system for transmitting moving visual images and accompanying sound to be received by a screen and loudspeakers. The term is used in Czech as well as in many languages to denote both the medium and the physical television set. The word derives from tele- meaning distant and visio meaning seeing.

The development began in the early 20th century with experimental broadcasts and mechanical and electronic systems. Early pioneers such as John Logie Baird and Philo Farnsworth contributed to the creation of television; commercial broadcasting began in the 1930s and 1940s. By the 1950s color television became common in many markets, and households gradually transitioned from black-and-white to color sets.

Technically, televize has evolved from analog broadcasting to digital signals. Analog systems transmitted over-the-air or via cable or satellite, at various standards (NTSC, PAL, SECAM). Modern broadcasts rely on digital standards such as DVB-T/T2 in Europe, ATSC in North America, and ISDB in parts of Asia, often combined with satellite and IPTV delivery. Displays progressed from cathode-ray tubes to flat panels using LCD, LED, OLED panels. Smart TVs connect to the internet to access streaming services and apps.

As a mass medium, televize has influenced entertainment, news, and advertising, shaping public opinion and culture. In recent decades, on-demand streaming and online platforms have competed with traditional broadcast, while public broadcasters continue to provide educational and cultural programming. The future of televize involves higher resolution, interactive services, and integrated digital ecosystems.
