Nearly a third of TV viewers believe that the quality of programming is falling, according to the latest Ofcom report.
UK audience attitudes towards broadcast media found that 30 per cent of adults believe content quality worsened in 2015.
An increase in repeats (65 per cent), a lack of variety (39 per cent), and an overall lack of quality (32 per cent) were cited as the main reasons for the fall.
Only 17 per cent believed that quality had improved throughout the year.
Participants were surveyed on a range of topics including the quality of TV programmes, whether they had found anything on TV to be offensive, and their opinion on the amount of sex, violence and swearing.
More than one in ten (12 per cent) of all adults who thought programmes had got worse said this was due to an increase in bad language.
Nineteen per cent of adult viewers in the UK said they had personally found something on television offensive in the past 12 months - a figure that remains largely unchanged since 2010.
