The original version was just for email. The first time o saw one was in 1999 at Nasdaq. Their CIO carried one. He was always testing new technologies. I remember they had a pilot project where they sent stock quotes over TV signals using the channel designed to carry closed caption information.
Yeah, so we had that in the UK in the 1970's, it was called Ceefax. But you shit-hole country types took a while to catch up.
