How Does Eurovision Voting Work?

Starting right in the beginning of the show when the first representatives of countries take the stage, viewers in all 39 participating countries can start voting by making a phone call and/or sending an SMS for their favorite song(s). You are allowed to vote up to 20 times, but you cannot vote for your own country
Based on the amount of votes by phone and/or SMS, televoters in each country then give 12 points to the most popular entry, 10 points to the second most popular, then 8, 7, 6, 5, 4, 3, 2 and 1 points
Each country has a professional jury also. Just like the televoters, each jury in each country then gives 12 points to the most popular entry, 10 points to the second most popular, then 8, 7, 6, 5, 4, 3, 2 and 1 points
Both sets of results are then merged. Each result counts for 50%
Spokespersons in all participating countries will read out the merged results, giving 12 points to the most popular entry, 10 points to the second most popular, then 8, 7, 6, 5, 4, 3, 2 and 1 points
