While "Pac-Man" was the best-selling title on the Atari 2600, selling about 7.9 million units by the end of 1983, Atari reportedly had expected to sell up to nine million units. After being critically panned, Atari had to deal with the returns of a large volume of unsold games, some which would end up as part of the Atari video game burial in September 1983. On December 7, 1982, Ray Kassar announced that Atari's revenue forecasts for 1982 were cut from a 50 percent increase over 1981 to a 15 percent increase. Following the announcement, then Atari parent Warner Communications' stock value dropped by around 35 percent—from $54 to $35—amounting to a loss of $1.3 billion in the company's market valuation. Atari attempted to regain its market share by licensing popular arcade games for its consoles. The revenue from selling these console games did not reverse Atari's decline and the company went further into debt. Atari ultimately reported a $536 million loss in 1983, and Warner Communications sold off the company's consumer division in 1984 to Jack Tramiel of Commodore International.
