late 1987 - this year changed many of the technologies that had become typical in the past. The Cellular Technology Industry Association (CTIA) was developed to lay down practical goals for cellular phone providers. This included research for new applications for cell phone development. A new standard was placed with the creation of the TDMA Interim Standard 54, in 1991 by the Telecommunications Industry Association.

In spite of the unbelievable demand, it took cellular phone service 37 years total to become commercially accessible in the US. According to the Cellular Telecommunications Industry Association, today there are more than 60 million customers with cellular phones, even though wireless service was just invented nearly 50 years ago. The cellular business was a $3 million market 25 years ago and has grown increasingly to close to a $30 billion per year industry.
