When was bitmap made?

The concept of a bitmap, which represents images as a grid of individual pixels, dates back to the early days of computing. The term "bitmap" itself became widely used in the 1970s, particularly with the development of the first computer graphics systems. Notably, the first bitmap graphics were utilized in the late 1960s and early 1970s, with early implementations in programs like "Sketchpad" developed by Ivan Sutherland in 1963.
