The Motorola DynaTAC 8000x was very large compared to phones today. This first cell phone was very expensive when it was released in the US in 1984. The DynaTAC's retail price, $3,995 (about $ in ), ensured that it would not become a mass-market item (the minimum wage in the United States was $3.35 per hour in 1984, which meant that it required more than 1192 hours of work, or almost 20 months - just working for the phone, without taxes); by 1998, when Mitchell retired, cellphones and associated services made up two thirds of Motorola's $30 billion in revenue.
