TV ads influence a larger proportion of online consumers to purchase a product or service than a variety of other advertising media, finds ExactTarget [pdf] in an April 2012 report. 53% of respondents said a TV ad had influenced them to purchase a product or service in the past 12 months, putting TV ads far ahead of newspaper ads (32%) and magazine ads (30%). In fact, three times more respondents said they had been influenced by a TV ad than by a banner or other ad on a website (53% vs. 18%). Radio ads (16%) also influenced twice as many respondents as video ads on YouTube or billboard ads (both at 8%). Read the rest at Marketing Charts.
