Because the chassis slides out the front, like a drawer. These sets were designed using modules that could be replaced for easy service. The first WID models, which were branded "Quasar" by Motorola, came out in '67 and were fully solid state (except for the HV rectifier tube). Actually, these were the first solid state color TV's that were sold in the US.

There were also tube/transistor hybrid versions of the WID sets. There were still some WID sets built, even after Matsushita bought the consumer electronics division of Motorola in '74. I think the WID concept was phased out by 1980.
