Superstars regularly attracted over 10 million TV viewers in the UK and Jacks became a household name, appearing on children's TV shows and picking up endorsements usually beyond the reach of a minority sport participant. Superstars also expanded again in 1980, adding International Superstars to its list of programmes, though this was as a direct replacement for the European event. Although popular in the UK, US, Ireland, New Zealand, Sweden, the Netherlands and Australia, Superstars reached its peak at the turn of the decade, and one by one (starting in Europe) the participating nations fell away.
