The options that people have to gain access to biritsh tv abroad are quiet numerous. However some of the techniques that can be used require a lot of capital investment. For instance the use of satellite connection is an expensive affair that is only feasible for those who have the colossal sums of money required for it.
Apart from the fact that satellite connection is capital intensive its reliability is questionable, this is because in a country where there are some government policies that restrict access to foreign TV then one might find that s/he cannot access British TV using the satellite.
Additionally the satellite can be a big burden when the user has to move to another country. This is because the user will have to move with the satellite dish or alternatively find a buyer for it. In such a situation a buyer will often offer a very low price as the seller is desperate.
