This is a fare point, and of which if the UK goverment wishes to fund. But this should not be done through TV licensing. The general public have a right to choice. If UK interests wish to be applied abroad then this can be through the appropriate goverment deaprtment which is funded through general taxation.
Albeit the commercial advatages that can be brought to countries around the world through commercial advertising therfore will fund the BBC broadcasting interests abroad. taking into account the license fee pays for these staff news offices around the world. As far as I am concerened this adds even more reason as to the BBC should be commercialised through commercial advertising. Taking into account the viewers and radio listeners around the world do not have to pay the BBC license fee. The UK resident is funding the world population who use BBC services through the £145.00 license fee.
