TTX reader

TTX readers are teletext readers, who are users of TTX with a minimum usage time of one second. Each person who uses the TTX for at least one second consecutively is counted as a reader for this medium. It is calculated in a similar manner as for television usage (but without the condition of minimum usage of one minute consecutively). Thus, it is a net value. The market share for TTX is calculated on the basis of viewing duration, analogously to the calculation of market share for television.
