The company incorporated the next year in California. Mattel became the first year-round sponsor of the Mickey Mouse Club TV series in 1955. The Barbie doll debuted in 1959, becoming the company's best-selling toy in history. In 1960, Mattel introduced Chatty Cathy, a talking doll that revolutionized the toy industry, which led to pull-string talking dolls and toys flooding the market throughout the 1960's and 1970's.

The company went public in 1960, and the New York Stock Exchange listed them in 1963. Mattel also acquired a number of companies during the 1960's (see table).

In May 1970, Mattel formed a joint venture film production company Radnitz/Mattel Productions with producer Robert B.

In 1979, through Feld Productions, Mattel purchased the Holiday on Ice and Ice Follies for $12 million. Also acquired that year was Western Publishing for $120 million in cash and stock. The Felds bought the circus (and related companies) in 1982 for $22.8 million.

New York venture capital firms E.M. Warburg, Pincus & Co., and Drexel Burnham Lambert invested a couple hundred million in Mattel in 1984 to help the company survive. However, the Master of the Universe action figure line sales dropped, causing a $115 million loss in 1987. Chairman John W. Amerman improved the company's financial performance in 1987 by focusing on core brands. Mattel returned to working with the Disney company in 1988.

In 2002, Mattel closed its last factory in the United States, originally part of the Fisher-Price division, outsourcing production to China, which began a chain of events that led to a lead contamination scandal.

Many of the products had exceeded the US limits set on surface coatings that contain lead. Surface coatings cannot exceed .06% lead by weight. Additional recalls were because it was possible that some toys could pose a danger to children due to the use of strong magnets that could detach. Mattel re-wrote its policy on magnets, finally issuing a recall in August 2007. The recall included 7.1 million Polly Pocket toys produced before November 2006, 600,000 Barbie and Tanner Playsets, 1 million Doggie Daycare, Shonen Jump's One Piece and thousands of Batman Manga toys due to exposed magnets.

Mattel had only sold Cinderella, Ariel, Belle, and the two Frozen princesses during the last year or so of its license.
