According to a comScore report, about 1.4 trillion of all 2012 ad impressions came during the fourth quarter of the year.
Three out of 10 display ads were never rendered in-view in 2012, according to a comScore report.
The report found that around six trillion ad impressions were seen last year. ComScore's report also covered 2012 trends in a variety of other markets like mobile and social networking. The 2013 U.S Digital Future in Focus report comes as part of an annual study by the research firm.
"ComScore research showed that an average of 3 in 10 ads are never rendered in-view, leading to significant waste, weaker campaign performance and a glut of poor-performing inventory that imbalances the supply-and-demand equation and depresses CPMs," said comScore in the report.
According to the report, about 1.4 trillion of all 2012 ad impressions came during the fourth quarter of the year. That figure represents a 6 percent year-over-year increase for the quarter.
Looking to 2013, comScore projects that publishers will begin to better use data to cut down on frivolous display ads. The firm projects that marketers will begin to use more targeted ads and use data that better shows the monetization ability of advertisements.
The new year projects to be a turning point for mobile. According to comScore, smartphones penetrated over 50 percent of the U.S. market in 2012. Over 52 million U.S. consumers also owned a tablet by the end of last year.
ComScore says last year's mobile device sales prove that media consumption is being fragmented across multiple screens. The firm's stats serve as a reminder to marketers that it's key to campaign across a variety of platforms.
According to the report, Facebook is quickly taking over consumers' free time. ComScore says that five out of every six minutes spent on a social networking site is on Facebook.
ComScore says that Facebook's growth and recent unveiling on Wall Street will be a boon for advertisers. The firm also expects Facebook to improve its standing on the stock market moving forward.
"2013 is poised to be digital's most exciting year yet as the growing ubiquity of digital platforms presents marketers with nearly endless opportunities to connect and engage with consumers," says comScore CMO and EVP of Global Product Development Linda Abraham.
"It's clear that the dynamics of the marketplace have fundamentally evolved through the adoption of smartphones and tablets and the increasingly 'digital' nature of all media. Navigating this changing landscape requires a holistic understanding of the key trends, underlying drivers and new opportunities that the digital ecosystem will bring in the year ahead."
