Comcast's NBCU books $250 million in profit from Rio Olympics coverage

(Reuters) - NBC Universal, a unit of Comcast Corp, said the company booked more than $250 million in profit from the Rio Olympics coverage, helped by strong advertising sales. Advertising sales rose more than 20 percent to $1.2 billion, compared with the 2012 London Olympics, NBC Universal Chief Executive Steve Burke said on Wednesday. Despite a drop in viewership, NBC had said in August that it could top the $120 million profit that it had recorded from the 2012 Olympics coverage.
