Americans are saying goodbye to text messaging, a wireless industry group has said.
A report found Americans sent 2.2 trillion text messages last year - down 5% from 2011, but still the equivalent of 19 text messages per person per day.
Text messages vaulted into the mainstream in 2007, despite often costing 10 cents (7p) each. Costs came down quickly as phone companies started selling monthly "bundles" of texts.
Now, many phone companies give text messaging away for free as part of a plan that mainly meters data used.
That has helped stave off mass migration to internet chat applications and Facebook messaging, but texting is still declining in popularity.
