TechCrunch has learned that CityGrid Media, the parent of local ad-based listings portals CitySearch, Urbanspoon and Insider Pages, is laying off two-thirds of its staff, or around 130 people. IAC, which owns CityGrid, confirmed the number to us and described the process as “streamlining.” The layoffs are taking place amidst another big shift at CityGrid: Andrew Moers, president of another IAC subsidiary, Ask Partner Network, is taking over as CEO. This is, however, only a temporary move: Ron LaPierre, who has been acting CEO since April, is taking a leave of absence for family matters and is expected to return in August.

“We can confirm that there has been a reduction in staff at CityGrid Media. The layoffs will increase operating efficiency, reduce costs and have a meaningful impact on the company’s future profitability,” a spokesperson said.
