People didn't want to be seen on the phone in the 1950s (or the 1960s or the 1970s), but they did seem open to the idea of appearing on their computer screens at work. The Model 70 not only made simultaneous video communication possible, it offered its callers the ability to open, view, and edit files, as well as annotate and write comments on the screen with a mouse or keyboard commands.
