TV shows etc, normally targetted at
teenagers, persistently demanding viewers to send text messages from their mobile phone (cellphone), either to win prizes or simply cast a
vote (for their favourite contestant, for example).
Some TV programmes seem to exist for this sole purpose, with a flimsy game show format as the pretext for the programme, which is really quite incidental to the persistent demand to text
the show. Texts are normally charged at "£1, plus your standard network rate."
