In the course of a comprehensive community reform in 1975, Wattenscheid, a formerly independent city, was integrated into the city of Bochum. A local referendum against the integration failed. In 2007, the new synagogue of the Jewish community of Bochum, Herne und Hattingen was opened. In 2008, Nokia closed down its production plant, causing the loss of thousands of jobs, both at the plant and at local suppliers. 20,000 people showed up to protest against the closing. Within months, the Canadian high-tech company, Research in Motion, announced plans to open a research facility, its first outside Canada, adding several hundred jobs.
