The document summarizes the history of cell phone costs from the 1970s to present day. Early cell phones in the 1970s and 1980s cost thousands of dollars, making them luxury items available only to few. Prices dropped in the 1990s as companies subsidized costs through service contracts, bringing cell phones within reach of many consumers. Smartphones emerged in the 2000s, led by Blackberry, iPhone and Samsung Galaxy, with prices ranging from $350-600. Today cell phones have become essential devices that are more like computers and cost a few hundred dollars or less with a service plan.
