American Text Messaging Volume, 2008-2013 [CHART]
Texting is the most common activity on a mobile phone after talking, accounting for roughly 1 in every 7 minutes spent on a mobile phone, per data from Nielsen. Recent research from Experian Marketing Services suggests that 18-24-year-old smartphone owners send and receive an average of almost 4,000 text messages per month. But texting may be on the decline: last year, Americans texted each other 2.19 trillion times, down 4.9% from the prior year, after at least 3 consecutive years of growth, according to [PDF] survey results from CTIA-The Wireless Association..
Prior to 2012, texting had grown year-over-year by 12.3% (2011), 31.3% (2010), and 55.5% (2009). Those declining rates of growth with each passing year were finally capped off by negative growth last year. Read the rest at MarketingCharts.
