ELI5: Exactly how useful is a constantly scrolling stock ticker, like one would see on the side of a building or on the bottom of a TV news network, to a modern investor?

Thanks to the internet and modern electronic trading platforms, any stock price is available instantly with a simple search. Is the scrolling ticker feed showing price updates that runs at the bottom of CNBC or on the side of some buildings in NYC still a useful tool in 2018?

its mostly anachronistic at this point.  even calling it a ticker is from when it came across the wire and was typed out with a telegraph.  ticker tape parades were just bunches of this paper being thrown out the windows onto parade goers.  i think people mostly use them now as an historical nod to the market rather than any useful purpose.  kind of like having a big clock in a train station- everyone has a clock in their pocket, but it is still there.
