Cellphones have become a major part of our life and the U.S. government has stats that prove it. The NCHS is part of the Center for Disease Control and Prevention and they have announced that 25% of Americans have given up their landline and have replaced it with a cellphone. 21,375 households were polled, which amounted to 40,619 adults and 14,984 children under 18. During the last half of 2009, 24.5% of households had only a cellphone. That is a 1.8% increase over the first half of last year. Additionally, 1 out of 7 Americans use a cellphone as their primary telephonic instrument despite having a landline. This is probably great news for U.S.carriers and cellphone manufacturers as it shows a large number of landline users that can decide to cut the wire and become cell-only callers.
