Nielsen has acquired gaming industry intelligence firm SuperData Research to give its ability to track games and esports a boost. According to its announcement, the acquisition will allow it to keep a closer eye on digital gaming use, sales and audiences. It will also give the company a way to track spending on esports events, tickets, marketing and sponsorships. In other words, SuperData will beef up Nielsen's capability to measure various metrics other than sales alone for an industry where those metrics matter. VentureBeat notes, though, that it doesn't always have the most accurate figures.
