Cell phones have taken the place of traditional phone lines.
Almost every American has a cellphone, 96 percent according the wireless industry.
Many cellphone users are thinking about making it their only phone and ditching their home landline.
New research from the Centers for Disease Control and Prevention reports 27 percent of U.S. households were using cellphones exclusively in the first half of 2010.
That's an eightfold increase since 2004.
Arkansas and Mississippi are leading that the trend.
The CDC's research shows 35 percent of adults in those two states have cellphones but not wired phones.
Eight other states have at least 30 percent of adults going the cellphone only route, but New Jersey and Rhode Island are at the opposite end of the spectrum.
There, only 13 percent of adults have dumped landlines.
But as cellphone service gets more dependable and more versatile, landlines are likely to go to the way of black and white television.
