§ Mr. ColvinTo ask the Secretary of State for the Environment what information he has about the effectiveness of the Government television advertising campaign on unleaded petrol.
§ Mrs. Virginia BottomleyIn a survey conducted during the week commencing 21 April, 60 per cent. of those interviewed, when prompted, were aware of the advertisement. This put it in the top 10 TV advertisements most remembered by the public.
The advertisements ran from 1 to 14 April and were shown on all commercial TV stations in the United Kingdom. It is estimated that 76 per cent. of all adults had the opportunity to see them at least once and 33 per cent. at least four times. On average the target audience of all motorists responsible for purchasing petrol had four opportunities to see the advertisement.
The unleaded petrol share of the market has increased dramatically from 6.4 per cent. in March to 19.3 per cent. in May.
