Finding Ghosts

There are a lot of puesdo reality shows of people searching for ghosts lately, but how come they don't find anything. One possible
answer is cellphones, yes cellphones.Remember there were no ghost hunting shows before cellphones.

 What does cellphones have to do with anything ,well cellphone numbers are usually not listed, but landline phone numbers are, unless of course it is an unlisted number.

People who hunt ghosts are actually wasting their time going to suppose haunted houses and other bulidings; But they did ever think of looking in the phonebook?

As you can see in this 1960's phonebook the number is listed.

To me all episodes of hunting ghosts are all the same.
