According to a new Nielsen report, display advertising – including banner ads – grew 26.3% in the first quarter, led mostly Asia-Pacific and Latin America, where display advertising grew 33.2% and 48.2%, respectively. The one major caveat to the study is that Nielsen hasn’t developed a system to measure search and mobile, as accurate tracking of those categories is difficult. Nonetheless, the display advertising figures reported by Nielsen are in line with other researchers’ numbers as well; the IAB reported that display advertising grew by 9% in the US in 2012, which fits with the Nielsen numbers. It still appears, however, that TV will retain its overall dominance in ad spending – at least in the short term.
