Direct retail sales are poised to represent less than half of Amazon's business for the first time in its history — a fundamental shift that reflects the e-commerce giant's expansion beyond its roots as an online store.

Revenue from Amazon Web Services, Amazon Prime, third-party seller services, online advertising and other services added up to 49.3% of Amazon's business in the second quarter. It almost matched the company's revenue from online and physical stores, and appears to be on a trajectory to surpass them in the future.

That's one of several takeaways from Amazon's second-quarter earnings report, released Thursday afternoon. On this episode of Day 2, GeekWire's Podcast about everything Amazon, we nerd out over Amazon's numbers.

Joining GeekWire co-founder Todd Bishop for the discussion are two online retail industry veterans who pay close attention to Amazon's business:
