"This year over a million adult Americans will share in one of the greatest pleasures in life - studying something new and fascinating, or learning more about a subject that deeply interests them. They will sharpen their job skills or learn valuable new ones, master foreign languages or become absorbed in new hobbies, learn to play musical instruments or increase their knowledge of world affairs. The amazing part of all this is that most of these Americans will gain their knowledge right in the comfort of their own living rooms. For they have discovered - and explored - the limitless opportunities for learning at home."
