I want to know the answer to the following question:
By what percentage has viewership in the US risen from 2012 to 2015?
All the background I'm provided with is that "Premier League viewership has increased rapidly, with NBC and NBCSN averaging a record 479,000 viewers in the 2014–15 season, up 118% from 2012–13 when coverage still aired on Fox Soccer and ESPN/ESPN2 (220,000 viewers), and NBC Sports has been widely praised for its coverage.". Is that enough to answer the question?
