Cell phones took 25 years to become overnight success!

Cell phones are thought of as a modern innovation, but the fact is that the first portable telephones appeared on the market in 1979, mounted in cars.

The first personal phone was the NTT "shoulder phone", which weighed seven pounds!

Mobile phones really began to take off in 1991, when NTT released very light models that weighed only 220 grams (about a half pound).

In 1993, what were called second-generation of cell phones hit the market.
In comparison with first-generation phones, these new models offered much clearer sound quality, and the problem of having the signal cut off when many users congregated in one area was overcome.

According to a recent study by consulting firm Deloitte & Touche, the global mobile phone market is set to grow to two billion subscribers by the end of '05, fuelled by strong demand from developing economies in Asia and Latin America.

Mobile penetration would surpass 100% in some markets as users take a second connection for data or for personal use.
