Electronics store RadioShack filed for a second bankruptcy in two years, forcing the retailer to close down 200 stores. The retailer originally filed for bankruptcy in 2015 and was acquired by General Wireless, a venture of Standard General hedge fund and Sprint. General Wireless announced on Thursday that it will be filing for bankruptcy in Delaware. Following the closures, about 1,300 RadioShack stores will remain open. The chain retailer was founded in 1922, and since the 2015 bankruptcy has been operating as a private company.
