Toplines of Research Findings - A large-scale continuous tracking survey of radio and TV
This Millward Brown study involved nearly 5500 interviews in continuous research to track awareness and attitudes to 17 brands. The media tested were Commercial Radio and TV in the Central Region of UK. - Adding radio to TV has a 15% multiplier effect
If 10% of a given TV budget is re-deployed onto radio, the efficiency of the campaign in building awareness increases on average by 15% - Radio in isolation was measured to be three-fifths as effective as TV at raising advertising awareness
On average, in this test, radio was three-fifths as effective as TV at increasing advertising awareness amongst an audience of 16-44 year old radio listeners - But this radio effectiveness result was achieved at one-seventh of the cost
On average, in this test, radio prices were about one-seventh of those for TV. While the price relativity for other audiences will vary, the achievement of three-fifths of the result at one-seventh of the cost makes radio significantly more cost effective than TV.Obviously price variance between radio and TV will vary depending on area and audience. - More effective radio campaigns
The most effective radio campaigns outperformed even the average for TV. Enjoyability is an important factor but, above all, the best-performing ads are well branded - Misattribution
There is clear evidence that consumers often think they have seen a campaign on TV when in fact radio was the only advertising medium used; splitting the sample into listeners and non-listeners helps to offset this misattribution
Research Summary
This study was devised to find out how effective radio advertising can be relative to TV, and to learn more about what kind of radio advertising is more effective: effectiveness was gauged in terms of measuring increases in advertising awareness.
The study tracked perceptions amongst consumers aged 16-44 for seventeen brands advertised in two comparable regions. For each brand, one town had radio advertising while the other did not. TV advertising was the same across both towns.

Millward Brown, who conducted the study across October 1999 to April 2000, model effectiveness in terms of the Awareness Index
Across the seventeen brands:
- the average Awareness Index for radio was 3
- the average Awareness Index for TV was 5
Therefore radio was, on average, three-fifths as efficient as TV at driving advertising awareness amongst radio listeners.
In terms of price advertising agency Universal McCann, advise that for the TG 16-44 Yrs, TV is around seven times the cost of radio. So, by achieving three fifths of the awareness at one seventh of the cost, the radio campaigns were significantly more cost-efficient than the TV campaigns.Obviously price variance between radio and TV will vary depending on area and audience.
This cost effectiveness advantage means that radio has a multiplier effect when added to a TV schedule. If 10% of a given TV budget is re-deployed onto radio, the efficiency of the campaign in building awareness increases on average by 15%.

Some radio campaigns performed much more strongly than others - indeed the strongest outperformed the TV average.
Radio campaigns with higher scores were characterised by good branding - these were campaigns where consumers were in little doubt which brand was being advertised. Enjoyability was also a characteristic of the better performing campaigns, although this could not overcome weak brand linkage.
Branding and enjoyability appear to be significantly more important factors than spot length or media laydown.
Proprietary branding devices (e.g. jingles, theme music) were strong contributors to the effectiveness of radio advertising, even though they may have originally been established on TV.

Misattribution is an important issue. Consumers may think they have seen a campaign on TV even when it has only run on radio. This has important implications for measuring the effect of radio - most importantly, research samples need to be split into listeners and non-listeners.
