The writer of a review article in the IT area depends on a variety of information sources containing authoritative material, hyped‐up reports, or even partial or pure fiction. Sometimes articles are biased or the author has a particular axe to grind — for instance the person is associated with a company and the article is no more than a dressed up sales piece. Academics are usually reliable — although unlikely to damn themselves with faint praise if the next grant is round the corner. I will try to exercise good judgement when assessing my information sources, supressing my various prejudices if possible. But what is meant by the word new? For the purposes of this article ATM (Asynchronous Transfer Mode) protocol (rules) and ATM switches in broadband networks, and aspects of Cable‐TV and cable modems have received a lot of exposure. They will not be discussed here. However, there is much interest in the contest between fibreoptic systems to the home and the conversion of telephone lines to wideband lines. These topics will be discussed.
