The ABC broadcast also began to use Chyrons, which "generated brightly colored maps, charts, graphs, and illustrations and imposed text over pictures. A red slash, like the one on the cover of Time magazine, was superimposed on stories, in an effort to give ABC's newscast a distinctive identity."

In the days before desktop video production software, such as Final Cut Pro and After Effects, making even a simple black and white title was a tough business. Creating broadcast-quality video titles required a specialized piece of expensive equipment called a Chyron generator and a highly skilled Chyron operator to run it. In fact, there was a time when Chyron operators made a good living because they were the only ones who knew how to make good, professional quality titles.
