The ailing UK newspaper advertising market is set to get even worse next year with national titles forecast to face an almost 9% decline that will see display revenue fall below £1bn for the first time, according to Sir Martin Sorrell's Group M.

Despite a slight improvement in the outlook for regional newspapers in 2013, a second year of double-digit ad decline will see advertising in this sector also dip below the £1bn mark for the first time. In 2005 the regional newspaper advertising market was worth more than £2.5bn.
