Running out of films for T.V. Channels

Whilst scanning through the Radio Times I have noticed  that several channels show the same film in one week.To me,this indicates that since we now have many channels there are not enough films being made to cope with this situation.My all time favourites are the splendid westerns,which the American film industry used to produce at one time.I feel quite sad that they no longer make westerns,realising at the same time;that those great stars of the westerns;such as Gregory Peck,Burt Lancaster;and many other household names,are no longer with us,due to their great age or retirement,even death.In recent years we have seen excellent westerns,featuring the likes of Clint Eastwood.It would seem that there are no actors to carry on with such a great tradition,such as the great westerns,of yesteryear.
