Happy 4th of July weekend! American business is one of the things that makes our country great, so we’ve decided to re-air our Fortune 500-themed Fortune Live, hosted by assistant managing editor Leigh Gallagher.

At the top, we’ll discuss this year’s Fortune 500, the challenges facing the companies, newcomers on the list, and the women CEOs leading the Fortune 500.

Then, Editor Alan Murray and Assistant Managing Editor Brian O’Keefe discuss Walmart’s WMT 0.39% top spot on the Fortune 500. We also have a one-on-one discussion with Doug McMillon, Walmart’s CEO.

Senior Editors Jennifer Reingold and Andrew Nusca then discuss PepsiCo PEP 0.06% and Apple’s AAPL -0.53% spots on the 500, as well as the newer tech companies to join the list.

Closing out the show, Senior Editors at Large Geoff Colvinand Patricia Sellers highlight leadership within the Fortune500.
