Direct broadcast satellite (DBS) is a term used to refer to satellite television broadcasts intended for home reception, also referred to as direct-to-home signals. The expression direct-to-home or DTH was, initially, meant to distinguish the transmissions directly intended for home viewers from cable television distribution services that sometimes carried on the same satellite. The term predates DBS satellites and is often used in reference to services carried by lower power satellites which required larger dishes (1.7M diameter or greater) for reception. In Europe, the expression was common prior to the launch of ASTRA-1 in 1988 as there were two markets: the DTH market which required the larger dishes and the DBS (ASTRA) market which required smaller (0.9M dishes). As higher powered satellites like ASTRA came into operation, the acronym DBS gradually supplanted it.
The term DBS now covers both analog and digital television and radio reception, and is often extended to other services provided by modern digital television systems, including video-on-demand and interactive features. A "DBS service" usually refers to either a commercial service, or a group of free channels available from one orbital position targeting one country.

Commercial DBS services
Germany is likely the leader in free-to-air DBS, with approximately 40 analogue and 100 digital channels broadcast from the SES Astra 1 position at 19.2E. These are not marketed as a DBS service, but are received in approximately 12 million homes, as well as in any home using the German commercial DBS system, Premiere.
The United Kingdom has approximately 90 free-to-air digital channels, for which a promotional and marketing plan is being devised by the BBC and ITV, to be sold as "Freesat". It is intended to provide a multi-channel service for areas which cannot receive Freeview, and eventually replace their network of UHF repeaters in these areas
India's national broadcaster, Doordarshan, promotes a free-to-air DBS package as "DD Direct Plus", which is provided as in-fill for the country's terrestrial transmission network.
While originally launched as backhaul for their digital terrestrial television service, a large number of French channels are free-to-air on 5W, and have recently been announced as being official in-fill for the DTT network.
In North America (USA, Canada and Mexico) there are over 80 FTA digital channels available on Intelsat Americas 5, the majority of them are ethnic or religious. Other popular FTA satellites include AMC-4, AMC-6, Galaxy 10R and SatMex 5. A company called GloryStar promotes FTA religious broadcasters on IA-5 and AMC-4.
