As reported by Forbes' Tom Ryan:

"Recognizing the world needs less space for retail and more to store data, Sears plans to turn some of Sears and Kmart locations into data centers and disaster recovery spaces.

[The retailer] also plans to top many of its buildings with telecommunications towers."
