Most of the discontinued Keurigs are just older versions of their current machines. However, a couple of them are worth special note: The Rivo and the Keurig 2.0. The Keurig Rivo was the predecessor to the K-Cafe and K-latte. Unlike those machines, though, the coffee it made actually had the strength of espresso. That's because the Rivo produced 15 bars of pressure, much more than other Keurigs. The downfall of the Rivo came from two main problems. First, it used specialized K-Rivo pods, which didn't have the variety of other k-cups and were sometimes hard to find. Second, it was a direct competitor to Nespresso. In the end, consumers decided that Nespresso was worth it and Rivo wasn't. The Keurig 2.0 was Keurig's attempt at preventing third-party pods. It introduced a pod-scanning technology that made use of digital rights management (DRM) to ensure that only approved Keurig pods could be used. It was basically the same idea as the barcode-scanning technology used in Nespresso VertuoLine machines.
