Fort Worth Star Telegram: Less than a year after opening a smartphone manufacturing plant in far north Fort Worth to great fanfare, Google’s Motorola Mobility announced Friday that it will close the Alliance facility by the end of the year due to weak sales of the Moto X device and and the costs of running the 450,000-square-foot plant. The Moto X will be made elsewhere, including China and Brazil, the company said. A spokesman for Hillwood Properties, developer of Alliance, declined to comment on the closing, saying it was the business of its tenant. He noted that Alliance is home to about 37 million square feet of space in total and 365 companies. See full story.
