The past decade marked a significant period of shakeups among some of the world's biggest retail companies.

While several companies went bankrupt and closed their doors for good during the course of the last 10 years, others consolidated to grow stronger by expanding into new sectors and widening consumer bases. Walmart and Amazon each made several acquisitions designed to maintain their status as global e-commerce juggernauts. Meanwhile, US fashion brands teamed up in an attempt to build an American luxury conglomerate that might someday rival the likes of LVMH or Kering .
