Spielvogel's talents in the marketing industry were instrumental in helping to recover Israel's public image after the Lebanon War.

[8] He began his working career in 1950 as a copy boy in the news department, he then became a reporter, and eventually a six-times-a-week columnist for The New York Times, until 1960.

[9] Until 1980, Spielvogel was vice chairman, and a member of the executive committee and the board of directors of the Interpublic Group, with which he was associated for twenty years, one of the world's largest communications marketing companies.

At the time, Senator Charles Grassley put a hold on several ambassadorial appointments, including those of Spielvogel and Richard Holbrooke.

In response, the American Jewish Congress sponsored a conference in Jerusalem in 1983, chaired by Carl Spielvogel, to explore ways of improving Israel's tarnished image abroad.

The conference brought together top public relations and advertising executives from the United States, along with journalists and academics from both countries.

The conference also addressed the challenging issue of West Bank settlements, highlighting the need for a sophisticated PR campaign to present a balanced and positive image of Israel to the world.

[16] In 1984, building on the momentum from the previous year's conference, the American Jewish Congress organized a dinner event that successfully raised $200,000 to enhance the public relations skills of Israeli government spokespersons.

This initiative was part of a broader effort to improve Israel's image and communication strategy on the global stage.

The dinner honored Carl Spielvogel, a renowned advertising executive, and Barbaralee Diamonstein, a distinguished writer, for their contributions to the field of communications.

The funds raised were earmarked for the Hasbara Project, an internship program designed to train foreign service officers in effective communication techniques by placing them with American companies.

He has been elected to the board of many publicly owned companies, including the board of directors of Interactive Data, Inc. and Apollo Investment, Inc.[18] He had previously served as a member of the board of directors of CBS Market Watch, Inc.; Interpublic; Josephson International; CMA; Foamex, Inc.; the United Auto Group; Culligan Water Technologies; Alliant Foodservice, Inc., Barneys New York, Hasbro, Inc., Kraft International, Bank Hapoalim, International Creative Management, Manhattan Industries and The Franklin Corporation.

He served on the board of trustees of Eureka Communities, which worked to rebuild depressed inner city neighborhoods across the nation, "one leader at a time" for ten years.

The program is entitled "The Colin Powell Fellows," and two summer interns have been selected each year to serve at the U.S. Department of State.
