Some big challenges ahead for wired Internet service providers
"But as the chart above shows, even people with higher incomes are ditching their wired Internet access at similar or even faster rates compared with people who don't earn as much. In 2013, 8 percent of households making $50,000 to $75,000 a year were mobile-only. Fast-forward a couple of years, and that figure now stands at 18 percent. Seventeen percent of households making $75,000 to $100,000 are mobile-only now, compared with 8 percent two years ago. And 15 percent of households earning more than $100,000 are mobile-only, vs. 6 percent in 2013.
Stepping back a bit, as many as 1 in 5 U.S. households are now mobile-only, compared with 1 in 10 in 2013. That's a doubling in just two years."New data: Americans are abandoning wired home Internet - The Washington Post
