The Joy of Painting was hosted by Bob Ross and ran on PBS from 1983 to 1995. During each half-hour segment, Ross would instruct viewers in the art of oil painting by creating an entire landscape.
With a soothing voice, he would describe the subjects of his paintings in such terms as "happy little trees" and "pretty little mountains". He believed that everyone had inherent artistic talent and the potential of becoming an accomplished artist given time, practice, and encouragement.
Bob was fond of saying, "We don't make mistakes, we just have happy little accidents."
