Wal-Mart (NYSE:WMT) is struggling these days, having reported shrinking sales last quarter. And one of the bigger factors dragging down its results has been soft sales of electronics.

In the video below, Fool contributor Demitrios Kalogeropoulos discusses two companies that are looking to profit while Wal-Mart attempts to get revenue growth going again in that business. Amazon.com (NASDAQ:AMZN), for one, has been building out its warehouses so that quick shipments of heavy objects like TVs are getting more affordable for the online retailer. And GameStop (NYSE:GME), which accepts trade-ins for used video game hardware, should see a big spike in sales as gamers cash out on their older systems so they can purchase next-gen consoles this holiday season.

Ultimately, though, innovation is what motivates shoppers to shell out for new devices. And with plenty of fresh products set to be released over the coming months, electronics sales should rise for all major retailers, including Wal-Mart.
