There was little difference between the first Sony and the Philips WebTV set-top boxes, except for the housing and packaging. The WebTV set-top box had very limited processing and memory resources (just a 112 MHz MIPS CPU, 2 megabytes of RAM, 2 megabytes of ROM, 1 megabyte of Flash memory) and the device relied upon a connection through a 33.6 kbit/s dialup modem to connect to the WebTV Service, where powerful servers provide back-end support to the WebTV set-top boxes to support a full Web-browsing and email experience for the subscribers.
