Transparency of TV competitions

Normally, I avoid watching the TV reality/celebrity shows, where the outcome of who gets voted off relies upon telephone voting. The only exception is Dancing On Ice.

I have always wondered why none of the TV companies will show the actual number of phone votes each contestant gets. They used to do it many years ago. So why have they stopped? I am sure if the audience actually saw how many votes their favourite performer received, they would be more likely to pick up the phone and vote, if their favourite was in danger of being voted off the TV programme. Surely it would be in the TV programmmes interest to increase the revenue it gains from the phone calls, and also it would be more transparent about the voting process. Then they couldn't be accused of fixing the competititon.

I have left a couple of messages to the Dancing On Ice presenter Philip Schofield, in the hope he may redirect me to someone who could actually give a valid response to my question. Who knows, I might be lucky and get a reply from him!
