A recent post about crawling got me thinking.
Crawling text at one time was up and down, vertical. Movie and television credits used crawls, often done on crawl machines Today crawling is mostly right to left, horizontal, at the bottom of the screen. This was once called a "ticker tape". So crawls were once produced on scrolls that went on "crawl machines". Today scrolling is the same as crawling. In ProType titler, Vegas calls it "scrolling" in the collection effects for what was once a "ticker tape".
What do you call it?
