ITV's From the Heart evening did not attract the desired attention last night, overnight data suggests.
Only 1.08m (4.3%) watched Dermot O'Leary and comedians raise awareness for increased organ donation in the UK.
Julie Etchingham's Tonight programme, covering the same subject matter, aired in the 8pm hour to 2.07m (8.8%) despite a mega lead-in from ITV's soap hour.
Over on ITV3, 1.13m (4.8%) watched Lewis between 8pm and 10pm, peaking in the 9pm hour - showing the amount of affection for a programme which could end after seven series.
All of the terrestrial channels beat ITV's much-trailed campaign show with The Brain Doctors securing 1.49m (6.3%) for BBC Two, NCIS managing a decent 1.56m (6.6%) for Channel 5 (+1: 147,000) and One Born Every Minute picking up 2.07m (8.8%) for Channel 4 (+1: 460k).
While BBC One won the major primetime slots, the channel's performance was far from spectacular by its high standards as Holiday Hit Squad took 3.82m (16.3%) and DIY SOS: The Big Build logged 4.31m (18.3%).
Ricky Gervais sitcom Derek suffered a slight knock as 1.23m (6.7%) caught the third episode of the first full series, but the figure is above Channel 4's slot average. A further 171k watched on the broadcaster's +1 service.
Overall, BBC One topped primetime with just 18.7%, ahead of ITV's 13.9% (+1: 0.6%). Channel 4 finished strongly in third place with 7.1% (+1: 1.2%), beating BBC Two which had 6.5%, and also overpowering 5's 4.1% (+1: 0.3%).
