In 1997, the Eurovision Song Contest began to phase in public televoting to determine its winner, with a mass rollout beginning in 1998. Initially, televotes completely replaced the previous system, in which entries were scored by regional juries. These changes led to the increased prominence of "bloc voting"—in which a country's voting pattern would commonly favour neighbouring nations (such as Scandinavian, Baltic, Balkan, and CIS countries), and countries with similar cultures (UK and Ireland). From 2009 to 2015, most countries used a 50/50 split between a jury and televoting results. Since 2016, most countries still use a televoting process and a jury to determine the results, the votes are no longer combined and instead treated separately.
