Nielsen, the media-measurement juggernaut, announced that it is opening up its API for the first time. Nielsen made the announcement alongside many other groundbreaking launches and promotions as SXSW continues to heat up. With coverage in more than 100 countries, Nielsen maintains a treasure trove of data that developers have long been eager to get their hands on. With the API release, developers can begin to build applications directly off data that is generated and maintained by Nielsen.
