RadioShack, which has been in financial hot water for some time, will close its Gainesville location at Lakeshore Mall, though there is no timeline of when the closing will take place. The company has been in business since 1921 when it started as an electronic mail-order business in Boston, and was one of the first companies to mass market personal computers and later, mobile phones, according to its website. The business filed for bankruptcy earlier this month and is expected to shut down about half of its stores across the United States, The Associated Press reported.
