Alternative, and far more apt, title for the closest thing we British have to Micro$oft - British Telecom.
Rather similar to M$ in the sense of being a vast, anti-competitive and highly monopolistic empire, rather dissimilar in the sense that they've never actually done anything remotely positive for their users other than to relieve them of as much cash as they can and provide a service of very nearly the lowest possible quality.
The icing on the cake is that they then produce awful gooey TV adverts telling you how grateful you should be that you have no alternative.
