Final answer:
While historical data suggests that Internet advertising and mobile advertising, in particular, have experienced significant growth, surpassing other traditional media in ad spending, current data would be needed to verify that Internet advertising is still growing at a rate of more than 30 percent a year.
Step-by-step explanation:
Assessing the claim that Internet advertising is growing at a rate of more than 30 percent a year requires current market data and trends. However, historical data from eMarketer.com in 2014 pointed out that there was a significant increase in US ad spending with mobile advertising being a major growth driver, projected to surpass traditional media such as radio, magazines, and newspapers in ad spend. It's crucial to note the changing dynamics in digital marketing and the escalation of social media influence which have been pivotal in advertising growth. A survey by the Pew Research Center reported that a significant majority of adults engage in social networking, indicating a strong correlation with the Internet's role in shaping advertisement trends.
Given the dynamic and rapidly evolving nature of online marketing, combined with evidence from the past as well as current digital consumption and social media prevalence, it's conceivable that Internet advertising could experience substantial growth. However, specific current data would be required to confirm the claim. The increasing importance and power of the Internet and social media in campaign strategies cannot be overstated, as they offer an efficient means of targeting messages to a broad audience at a lower cost compared to traditional mass media.
