   • 2014, Jules Witcover, No Way to Pick a President:

     […] instead of thirties [thirty-second commercials], they buy sixties, which cost twice as much. They spend more on filming it than they need to; they buy a lot of ads that are garbage and don't really say anything, just to fill up the space.
