In 1976, Karvellas became the voice of the New York Cosmos, teaming up with Howard David on TV and radio. "Jim was the perfect man for those days. He had a lot of flair; he was a reflection of the team" said Cosmo's Giorgio Chinagila to the New York Post. Karvellas' intonation "This is Cosmos Soccer" became a catchphrase and the name of an album featuring highlights from the team's 1977 season.
