- Notable developments in 1973 included a major rule change allowing songs to be performed in any language for the first time, prompting Finland and Sweden to sing in English, and the debut of pre-recorded backing tracks (first used by the United Kingdom).
- Israel made its first appearance, becoming the first non-European country to compete, amid heightened security following the Munich attack.
- Malta withdrew late after judging its submitted songs too weak, while Austria stayed out due to broadcaster–record label disputes.
- Luxembourg won again, equalling France’s record four victories and setting a still-unmatched 80.63% of maximum possible points.
