(Reuters) – Best Buy Co Inc Chief Executive Hubert Joly said tablets sales were “crashing” and the PC business was seeing a revival in sales, according to the website, Re/code. The U.S. smartphone market has also grown more mature, Joly also said, according to the website. Best Buy had earlier warned that same-store sales could fall this quarter and the next on lower demand for many consumer electronics. Joly attributed the PC revival during the first quarter partly to Microsoft Corp stopping support for the older Windows XP operating system, the website said.
