The recent election may have made data, and facts in general, seem less important. But marketers still hunger for it. Location-based mobile ad network xAd just bought itself a heaping plate of data by purchasing WeatherBug, which has an app with more than 20 million unique users and a network of more than 10,000 private automated weather stations across the country. xAd also announced a new funding round of $42.5 million, raising its total to $116.5 million. Note that weather data and location data go hand-in-hand, especially when consumers are checking the weather on a mobile app.
