Name one consumer software company from the 1980's that still exists, besides Microsoft. Just down the road from me is Frontier, which was founded by David Braben. He was working on the original Elite back in the early 80s, and although Frontier didn't come along until a decade or so later and doesn't strictly meet your condition, I'd argue that it's a good example of a successful consumer software business and has got there by producing a sustained track record of successful products. A few years ago it was listed on the stock market, but by then it had already managed almost two decades as an independent and grown to hundreds of people.
