And now, a brief homage to the Vidifont.

No, I'm not ignoring the Chyron (or Chiron), but I have to take a moment here to share one of my prized chunks of early television nostalgia...a brochure for the device that first gave me hope that there was a way to display type on TV that didn't involve shooting it off off a black card with a camera.
The Vidifont. The original model, from CBS Labs, which became Thomson CSF Labs, which became, well, I've lost count. It's true that I did most of my work on the Vidifont IV (here's the actual unit I used at Atlanta's WTCG in the late 1970s), but my fascination with TV graphics began with this device.
Two hard-wired fonts, big and small, and by the way, the small one's all caps. Here's an excerpt from one of the brochure's documents:
The Vidifont system is a television titling system designed to eliminate the need for artwork or menu-board titling by providing the user with electronically-generated, instantly-available, quality characters. A complete Vidifont system consists of a basic Vidifont package, a storage system and miscellaneous accessories or options.
In Vidifont systems, fonts are stored in semiconductor read-only-memories (ROMs), factory-installed in the Vidifont. A basic ROM system includes a 28 scan-line high set of upper-case characters of proportional widths (CBS News 36). There are 62 letters, numbers, punctuation marks, and symbols in the set. Other ROM fonts are available as options.
The system allows display of up to 16 lines — or rows — of characters with as many as 32 characters per row. because of proportionally-spaced characters, the actual number per line will vary.
The basic system features two speeds of roll and crawl, three speeds of flash, as well as four-position pushbutton tabs and centering. The capability to colorize (word by word) and edge is built in, and may be tied to the optional Colorizer Keyer.
The basic system consists of at least three units, the Display Control Unit, Power Supply, and Composer Keyboard. The Display Control Unit (DCU) is a rack-mounted unit containing all the logic and memory circuitry to produce the electronic characters.
