He joined the Carson-Roberts Agency in Los Angeles in 1953 and later on became the president of the company until 1970 when it was bought by Ogilvy & Mather, where Schneider would work for the next 10 years.[1] In 1954, he was an Account Manager for Mattel in the Carson-Roberts Agency. In that same year Mattel spent $500,000 to sponsor the Mickey Mouse Club. Schneider was the first person to film a toy commercial.[2] From 1978 to 1980, Schneider was Ogilvy & Mather's senior vice president in New York City.
In 1980, Warner-Amex Satellite Entertainment Network hired Schneider to be the president of the then-new Nickelodeon network. Despite introducing popular programs such as You Can't Do That on Television to the lineup in 1981, Nickelodeon operated at a loss of $10 million, and at one point had the lowest number of viewers compared to other cable channels by 1984. In 1983, Bob Pittman was made head of MTV Networks and Schneider was not comfortable with his "idiotic" approach to "home-based" television. As a result, Schneider left the network in early 1984.[3]
From 1984 to his death in 1994, Schneider worked at Bozell, an advertising agency in New York, and served as its corporate vice president from 1988 until 1994.[1] In 1987, he wrote a book about children's advertising and programs called Children's Television: The Art, the Business and How it Works.[2]
