Screens & 2D Graphics: Crash Course Computer Science #23

Today we begin our discussion of computer graphics. So we ended last episode with the proliferation of command line (or text) interfaces, which sometimes used screens, but typically electronic typewriters or teletypes onto paper. But by the early 1960s a number of technologies were introduced to make screens much more useful from cathode ray tubes and graphics cards to ASCII art and light pens. This era would mark a turning point in computing - computers were no longer just number crunching machines, but potential assistants interactively augmenting human tasks. This was the dawn of graphical user interfaces which we’ll cover more in a few episodes.
