Netflix did not improve their mail order DVD business. Nothing about streaming improved their mail order dvd delivery. What you have uncovered is that successful cannibalization in a product area in retrospect can seem like product continuation and improvement. But at the time - absolutely not.

But assuming they won out, it would've just seemed like an evolution in video rental.
