The satellite dish TV is very similar to broadcast television. The only difference is, with broadcast TV, it can only pick up channels that can reach the broadcasting antenna while the satellite dish TV has greater range of channels. The viewers not only have the chance to watch a wide range of shows all over the country, but the satellite in the sky can also pick up on signals of international channels. 
Nowadays, the question is not which channel you should watch, but which TV service you should choose. DirecTV or DISH Network are just some of the cable companies that provide such service. The consumer or the customer gets to figure out what type of service they need based on their requirement.
It is pretty much like this analogy: You go to a dentist when you need their dental services. You go to a divorce lawyer when you need help in your divorce process. If you live in Melbourne, go to divorce lawyers Melbourne.
Since many people, on the average, spend as much as four hours in front of the television, a lot of them would consider getting a reliable and good TV service. For those who are budget conscious, they can opt to get a satellite TV instead of cable TV.
