It means fewer programmes of intellectual or educational worth replaced by reality TV and Soap Operas. Particularly reality TV gives people, often younger people, unrealistic role models for themselves, lifestyle and behaviour and often encourages them to value things which are frankly not very valuable. I think it creates insecurity and anxiety and leads people to obsess of unimportant things whilst they are blissfully unaware of the very important things. this clearly doesn't apply to everyone, but when you find that a huge percentage of people under 20 think Auschwitz is a beer, you really do have to wonder.
