An "unfortunate error" in a control centre led to ITV HD viewers seeing a car advert instead of an England goal during the World Cup, Ofcom has ruled.
The regulator received 823 complaints from angry viewers who missed Steven Gerrard's goal four minutes into the England v USA match on 12 June.
ITV said the incident had been caused after an advert break trigger was inadvertently activated.
It added it "deeply regretted" the incident and had apologised to viewers.
The unscheduled break began with a Hyundai sponsorship segment, followed by a series of black frames.
During the 21 second interruption, the goal was scored.
Viewers watching ITV1's standard service were largely unaffected.
ITV stated that it took additional measures after the incident to ensure it could not happen again, including manufacturing special covers to avoid accidental activation of equipment.
Ofcom took this into account and, in acknowledging that presenter Adrian Chiles made an on-air apology, considered the matter resolved.
