KNOWLEDGE CHECK! Which magazine publisher was the first to open a software house? If you said Thalamus, the label from Newsfield Ltd, then sit down because they weren't founded until 1986.
Mirrorsoft is not right but it's a better guess than Thalamus, as is Beyond Software, owned by East Midlands Allied Press (or EMAP to their friends), both companies were founded around the same time in late 1983. Obviously the correct answer is Argus Press Software because that's who this update is about.
