Shame there's not more pics for the article, especially internals, quite interesting machines. > The Universal Stock Ticker was developed by Thomas Edison in 1869, when he was just 22 years old and working for Gold & Stock Telegraph Company. This design improved on previous stock tickers, allowing for alphanumeric characters and printing one character per second. Updating the entire S&P500 at best every hour or so. Thankfully they didn't use xml!
