He was the chairman of Comcast Spectacor, a Philadelphia-based sports and entertainment company that owns the Philadelphia Flyers of the National Hockey League; the Wells Fargo Center; the regional sports network Comcast SportsNet; and Global Spectrum, an international facilities management company.

Snider was born to a Jewish family in the Washington, D.C. region, the son of a grocery-store chain owner.

[3] Snider started a record company, Edge Ltd., with his friend Jerry Lilienfield in the 1960s, which was moderately successful.

Snider was given an option to purchase a 7% stake in the team and eventually served as vice president and treasurer, running the day-to-day operations of the Eagles.

When Wolman placed the Spectrum in bankruptcy in 1971, Snider and Foreman took over the building, eventually paying off every creditor in full.

[5] Snider would found or acquire several businesses during his career, most notably a regional premium cable channel, PRISM, and the first all-sports radio station, WIP.

[citation needed] Prior to the Wells Fargo Center's opening in 1996, he sold a 66% stake of all of his businesses, including Spectacor, to Philadelphia-based Comcast, creating Comcast-Spectacor.

In a 1999 Philadelphia Daily News poll, Snider was selected as the city's greatest sports mover and shaker, beating out legends such as Connie Mack, Sonny Hill, Bert Bell, and Roger Penske.

The foundation donates millions of dollars annually to causes he believed in, including Jewish causes, conservative political organizations, and educational programs.

In 1989, Snider was inducted into the Philadelphia Flyers Hall of Fame alongside Keith Allen and Bill Barber.

After a months-long battle, Snider died on April 11, 2016, at his home in Montecito, California and was interred at West Laurel Hill Cemetery in Bala Cynwyd, Pennsylvania.
