Since 1998, the use of broadcast TV has fallen sharply, going down from 950 to under 600 hours in just seven years. This figure levelled off slightly in 2002 with a slight decline of just 30 hours compared to a sharp fall of 70 hours the following year and reaching an all-time low of under 600 hours per year by 2004. At the beginning of 2005, the use of broadcast TV has abruptly risen, only to be followed by a gradual drop in the second quarter.
