WorldCom began in 1984 as a small long distance provider called Long Distance Discount Services, and grew rapidly through acquisitions in the 1990s, changing its name to WorldCom and becoming the second largest long distance provider after merging with MCI in 1997. However, as the telecom boom ended in 2000, WorldCom's revenues fell short of expectations while debt from mergers remained high. In 2002, WorldCom admitted to fraudulently inflating earnings through improper accounting, including reducing reserve accounts by $2.8 billion and improperly capitalizing regular operating expenses. This caused its stock price to plummet from $64.50 to under $1, and it filed for the largest bankruptcy in U.S. history at that time
