TV is arguably the lone traditional medium that been able to retain its premium ad rates and audience reach (mostly), while other media have suffered fragmenting audiences and declining ad revenues. But the fact that millions still watch TV doesn't necessarily mean TV advertising has the power and impact it once did.
A recent study from ad network InMobi, involving 15,000 users from 14 global markets including China, Europe, the US and several African countries, argues that consumers now spend more time with mobile media than TV (there are competing data that show TV is still on top).
The survey found TV to still be the most influential single medium, followed by PC/online and then mobile. Other traditional media lagged behind in their influence over purchase decisions. The following reflects the percentage of survey respondents who reported that the medium "significantly influenced" their purchase behavior:
The data above are not broken out by country. Undoubtedly there would be variation, potentially significant variation, accordingly.
With respect to TV, however, users are now widely "second screening" -- that is, diverting their attention from the programming and advertising to focus on some activity happening on their smartphones or tablets. Two-thirds of the TV audience is now doing this on a global basis, with younger users (<35) being the most likely to multiscreen (graphic above).
What are they doing on those second screens? The survey says they're on social networks or otherwise messaging friends (see graphic below). Note that a substantial number are "searching for information about products" they saw on TV. This represents both a new opportunity for brands and TV advertisers generally.
Marketers now must be conscious that a significant portion, indeed the majority, of the TV audience is going to "look away" at their smartphones or tablets. Marketers must have a mobile optimized presence on search and social media. But beyond simple presence, TV advertisers need to make it easy for mobile users at home to find their products or services easily (the many hashtags used in Super Bowl TV ads is one example).
TV advertisers can drive email sign-ups/opt-ins, app downloads as well direct purchases with the right offers and TV-ad messaging. In addition, with coordination and planning mobile can be used to measure TV ad effectiveness as well.
The larger point is that fewer and fewer TV viewers (especially those under 35) are watching TV or online video without a mobile device nearby. That allows them to either take action on ads they see -- or totally ignore them.
