title: Display On-Screen Television Graphics During Live Broadcasts
body: <p>How and with what software do major television companies display on-screen graphics during their programs?</p>
  
  <p>For example:</p>
  
  <blockquote>
    <p>On ESPN, how do they produce the news
    ticker on the bottom (both graphically
    and from a source code point of view),
    create and display the scores of
    sports, and update and show selected
    stats on the fly?</p>
  </blockquote>
  
  <p>I've looked everywhere I can think of to find the answer, but I am at a loss.  That's where you guys (and girls) come in.  I hope you can help shed some light on this subject for me.  Thanks in advance.</p>
