In the Woking/Guildford area, it's hard to get away from Cable. Everyone has it. If you get a new house it will be cabled. Most your neighbours will have it.
They do advertise a lot. There are leaflets shoved through the door every other week, and in the newspaper. They advertise a fair bit on local radio and there are adverts on TV.
And yet still people pick ADSL or leave NTL to go for ADSL... hmm
