When I was young, back then in my primary school, when I was more or less 10 years old, I remember my favorite part during working days was special TV program for school kids broadcasted every day in morning hours with mixture of great educational documentaries and movies. After school we rushed home to watch those popular documentaries giving us maybe even better knowledge enriched with colorful multimedia experience than we could learn in school. I will always remember those days back in 70s and later in early 80s when black and white TV era ended and color TV entered the homes in great style, probably comparable to what internet added to home computers decade or so ago. The most memorable and probably the most popular TV show about nature, biology, zoology and science in general was "The World of Survival", British famous documentary of the time narrated by various famous people and promoted by naturalists like David Bellamy. I still remember and quote from time to time
