Britain's biggest free-to-air commercial broadcaster ITV has revealed that advertising revenues have continually risen this year which will, in turn, boost profits for 2013.

According to a company announcement, advertising revenues are expected to rise 2% on average for 2013, following a strong programme schedule in the final quarter.

ITV broadcasts drama blockbusters, such as Downton Abbey, and popular reality shows, such as I'm a Celebrity Get Me Out of Here.

It said advertising revenue rose 8% in October and was forecast to be up 4% in November and up 1% in December.

ITV also reported a 6% rise in total external revenues for the period, reaching £1.66bn (€2bn, $2.7bn), driven by strong growth in Online, Pay & Interactive and in ITV Studios.
