Season 1
The first season of Idols premiered in the summer of 2003 and like its sister shows around the world, was an instant ratings success. It was hosted by Ellen Jokikunnas and Heikki Paasonen, and the four judges were Finnish musician Jone Nikula, Helsinki Music Company executive Asko Kallonen, and Finnish songwriters and producers Hannu Korkeamäki and Nanna Mikkonen. The semifinals started on 12 December 2003 and on 9 January 2004 the grand finale was held at the Helsinki Ice Hall. Former forklift truck driver Hanna Pakarinen was declared the first Finnish Idol with 60% of the public votes cast, winning 30,000 euros and a recording contract with Sony BMG.
Winner Hanna Pakarinen released "Love Is Like a Song" as her coronation single after being crowned Finnish Idol. It debuted at number 1 on the Finnish singles chart, a position it held for four weeks. Her debut album When I Become Me was released on 9 June 2004 and it peaked at number 2 for five weeks. It was certified platinum and sold over 52,000 copies in Finland. Her second album Stronger was released in September 2005 and it too peaked at number two, however it did not manage to achieve the same commercial success of her debut, though it did earn gold status, selling almost 17,000 copies. Pakarinen's third studio album Lovers was released on Valentine's Day 2007 and was met with high critical and commercial success, with the album praised as her best to date and a clear change of artistic direction, with Pakarinen moving to a much rockier sound. Despite the fact that it charted lower than her two previous efforts (peaking at number 3), Lovers was active on the chart for fifteen weeks and was certified gold, selling 16,000 copies. Later in 2007 she participated in the Eurovision Song Contest with "Leave Me Alone", the second single from her third album and she finished the contest in 17th place. In January 2009 her fourth studio album Love in a Million Shades was released and charted at number 7, her lowest position to date. The album sold 7,000 and became her first album not be certified. Pakarinen's fifth studio album (and her first to be recorded in Finnish), Paperimiehen Tytär was released in October 2010 and debuted at number 9 on the albums chart.
Runner-up Jani Wickholm signed a recording contract with the RCA division of Sony BMG and his debut album Kaikki muuttuu was released in September 2004. The album held the number 1 spot for two consecutive weeks and was certified platinum, selling 30,000 copies to date. His second album Alumiinitähdet was released a year later, peaked at number 6 but sold only 6,000. His third and fourth albums (Yhden lauseen mies and Ranta-ahon valot) were released in January 2007 and April 2008 respectively, and were met with decreasing sales figures. Neither received a certification, with Yhden lauseen mies selling just 5,000 copies and Ranta-ahon valot fewer than 4,000. Wickholm released his first greatest hits compilation, Kirkkaimmat Tähdet in May 2010, but the album failed to achieve commercial success and as a result, missed the Finnish Top 50.
Third place finisher Antti Tuisku also signed with Sony BMG and has gone on to become the most commercially successful contestant in Idols history, with his albums sales higher than those of all his fellow season one contestants combined. His debut album Ensimmäinen appeared in May 2004 and peaked at number 1 for three consecutive weeks. It was certified double platinum, selling 71,000 copies. Antti Tuisku, his self-titled sophomore effort also hit the top spot when released a year later in May 2005, and was certified platinum after selling over 37,000 copies. He released a Christmas album, Minun Jouluni in November of the same year which was certified gold and peaked at number 3. On 4 October 2006 he released his third and fourth studio albums New York and Rovaniemi simultaneously. The former debuted at number 1 and the latter at number 2, making Tuisku the first Finnish artist to release two albums on the same date and have them take the two highest positions on the chart in their first week. New York proved to be more successful and sold 15,000 copies to be certified gold, whilst Rovaniemi sold just under 14,000. In November 2007 Tuisku released Aikaa, his first "greatest hits" collection. Unlike his previous studio albums which had all been top 2 hits however, it stalled in the chart at number 10, selling only 7,000 copies. His fifth studio album Hengitän was released on 23 September 2009, peaked at number 3 and was accredited gold for sales of over 15,000 copies. Tuisku's sixth studio album, Kaunis Kaaos was released on 27 October 2010 and debuted at number 2, Tuisku's highest chart debut since 2006. It was certified platinum for sales of over 20,000 copies. In addition to the success of his albums, Tuisku has also achieved three number 1 singles, more than any other Idols contestant.
Fourth place finisher Christian Forss signed with Edel Records and released his self-titled debut album Christian Forss in late 2004. Although it initially peaked at number 6 for two weeks, the album quickly fell down and left the chart after selling 13,000 copies and did not achieve gold status. His second album Hungry Heart was released a year later but achieved little commercial success and failed to chart on the Finnish Top 40.
Sixth place finisher Anniina Karjalainen independently released her first album Traces of Me in 2006 but it did not receive significant success, failing to chart and selling only 3,000 copies.
