As the global advertising market surpassed half a trillion US dollars in 2014, the United States remains unchallenged both in terms of total and per capita ad spend.
According to Strategy Analytics, advertising expenditure reached $181 billion in the United States last year, almost eclipsing the combined ad spend of the remaining Top 10 ad markets.
In terms of per capita ad spend, the US lead isn’t quite as impressive but still significant. With an average ad spend of $567 per capita, the United States edges out Australia and Norway with $486 and $472 per person, respectively. China, which recently surpassed Japan to become the second largest ad market overall, has by far the lowest per capita spending of the Top 10 markets.
