For many decades, television and data transmission have followed parallel but completely independent paths. Although television sets were used as the first home computer monitors back in the nineteen-eighties of the century now past, this was the only interaction between the two fields. Today, however, it is becoming increasingly difficult to distinguish between the two media of television and computers which are converging more and more in this age of multimedia. There are now excellent TV cards available for PCs so that the PC can easily become another TV set. On the other side, teletext was introduced back in the eighties to provide an early medium for supplementary digital information in analog TV. For young people today, this way of obtaining information forms such a natural part of their viewing, e.g. as an electronic program guide, as if there had always been teletext right from the beginnings of television.
