Televisiojakelulla refers to the methods by which television content is distributed to viewers. Historically, the primary form of television distribution was through terrestrial broadcasting, using antennas to receive signals transmitted over the airwaves. This method was prevalent for decades and allowed for widespread access to a limited number of channels.

In the latter half of the 20th century, cable television emerged as a significant alternative. Cable systems deliver television signals through a network of coaxial or fiber optic cables, offering viewers a much larger selection of channels compared to terrestrial broadcasting. This expansion in channel availability led to more specialized content and niche programming.

Satellite television represents another major distribution method. Signals are broadcast from a satellite in orbit to a parabolic dish antenna installed at the viewer's location. This technology is particularly effective in reaching remote areas where terrestrial or cable infrastructure is not feasible, and it also provides access to a wide array of international channels.

More recently, internet-based distribution, often referred to as Internet Protocol Television (IPTV) or streaming, has become increasingly dominant. This method utilizes broadband internet connections to deliver television content. Services like Netflix, Hulu, and YouTube TV allow viewers to watch live channels, on-demand content, and traditional programming over the internet, often on various devices beyond traditional television sets. This shift has fundamentally changed how and when people consume television.
