DynaTAC is a series of cellular telephones manufactured by Motorola from 1983 to 1994. The Motorola DynaTAC 8000X commercial portable cellular phone received approval from the U.S.on September 21, 1983. A full charge took roughly 10 hours, and it offered 30 minutes of talk time. It also offered an LED display for dialing or recall of one of 30 phone numbers. It was priced at $3,995 in 1984, its commercial release year, equivalent to $10,000 in 2020. DynaTAC was an abbreviation of "Dynamic Adaptive Total Area Coverage."

"A handheld portable phone was considered a gimmick, a "look what I got!" rich man's toy with dubious utility.

Measuring 13 x 1.75 x 3.5 inches and weighing 28 ounces, the 8000X was so big and heavy, even its creators had nicknamed it "The Brick."

  On March 6, 1983, Motorola officially unveiled the DynaTAC 8000X, but it would be seven months before the FCC gave the phone its blessing. On October 12, 1983, Ameritech initiated the first commercial cellular service in the U.S. Service cost $50 a month plus 40 cents a minute from 9 a.m. to 5 p.m., 24 cents a minute off-peak. Two months later, Cellular One launched its Motorola-designed DynaTAC network in Washington, D.C. and Baltimore
