NBC announces $1bn in ad sales for Rio Olympics

NBC has announced that sold advertising space for the Rio de Janeiro Olympic Games this summer has generated over $1bn. The $1bn includes national broadcast, cable and digital sales. A representative from NBC Sports Group expects ad sales to 'break revenue records', with numbers already surpassing those of the 2012 London Olympics.

Now NBC Sports can put a number on just how far ahead it is from four years ago: four months. NBC said this morning that it has surpassed $1 billion in national advertising sales for the Rio Olympics, four months earlier than the 2012 Games. NBC reached that mark July 25, 2012, just two days prior to the opening ceremonies.
