MINNEAPOLIS - It was 40 years ago that an executive with Motorola made the first known cell phone call. It was a simple phone call that has altered how we communicate.
"It has become a part of what we need. I have to have this, it has to go with me," said Michael Porter, Ph.D., director of the Master of Business Communication program at the University of St. Thomas.
A lot has changed since the first mobile phone came on the market.
They used to cost about $4,000, now they're around $200.They used to weigh two and half pounds and now phones are typically less than four ounces. The size has gone from nearly a foot to just under six inches.
But there a lot of things that can't be measured.
In Porter's teachings, he talks a lot about what the cell phone has replaced, from the traditional phone, to the camera, to the video and cassette recorder.
"And things we never imagined are in one little device," said Porter.
"It does everything," said Kristin Nohe, a cell phone user from Minneapolis.
Nohe says she got her first cell phone as a teenager after her parents made her because she was driving. Now she cannot live without it.
"I don't even need a note pad. I have it in the phone," she said with a smile.
Many love them, but others love to hate them.
"It's disconnected us spiritually for sure," said Congo Lohese, a Minneapolis cell phone user.
Lohese admits he would feel weird without a mobile phone on him, but he also feels there can be downfalls.
"You're at a table having dinner with friends. You send your friend a tweet from across the table," he said.
According to the U-N, of the world's seven billion people, six billion have mobile phones, but only four and half billion have access to toilets.
