NEW YORK — Evolving shopping habits have forced yet another retailer to think outside of the box.
Staples, the nation's largest "big box" office supply chain, announced Wednesday that it's spending about $6 billion to buy its second-ranked rival, Office Depot.
The acquisition reflects a reversal of fortunes for big-box retailers. Founded in the late 1980s, Staples and Office Depot were among a group of chains led by Wal-Mart that opened thousands of supersized stores during much of the next two decades for shoppers who wanted to buy in bulk.
But shopping patterns changed in recent years as Americans have grown increasingly deal-hungry and comfortable with online shopping. Competition from smaller stores and the rise of online retailers like Amazon.com also have hurt big-box chains.
Office supply retailers also have some unique issues, though. The impact of technology on the U.S. workforce has dramatically shrunk the demand for items that were once their bread-and butter, including personal computers, ink cartridges, and printers.
In the 1990s, office supply retailers catered to the throngs of workers setting up home offices. But, now with the popularity of smartphones, people can work anywhere. They also are buying fewer PCs and other big gadgets in favor of small devices like smartphones.
Staples has been ahead of its office supplies peers in responding to the changes. It's been changing its mix of products in the stores, beefing up services like copying and offering more items online. It's also been opening smaller stores and investing in services aimed at specific small businesses.
But the brick-and-mortar office supply chain business has continued to struggle as online sales have grown. Last year, office products sold online hit $9.2 billion, accounting for 24 percent of the overall office supplies category. That's up from $2.6 billion, or 7 percent of the market, in 2004, according to Forrester Research.
