a Saturday, in 1990 it was held on a Friday. TV2 suggested this would attract more viewers. In 1991, it was held on Easter Sunday for the same reason. The 2002 final was delayed by a week for coverage of the 2002 Winter Olympics. The competition has had an official website since 1999. Webcasts have been provided since 2005. Since 2006, between February and the Eurovision final in May, SR has webcast a radio station dedicated to the competition called P4 Melodifest. On P4, the public previews the heats participants every Friday. Broadcast the night after the final, a ("the day after") television programme acts as an epilogue to the event. It gauges the reactions of the finalists after the competition's climax. No commentary is given for the event on television. Carolina Norén is commentator on the event for Sveriges Radio. The festival has been broadcast in widescreen since 2002 and Dolby Digital since 2004. The competition's viewing figures have been rising since 2002. In 2007, approximately 4.1 million Swedes—almost 44% of the country's population—watched the final, and between 2.9 million and 3.2 million viewers watched each of the heats. The viewing figures for the 2007 festival are nearly two million short of the highest recorded viewing figures from 1990. Melodifestivalen is given heavy coverage in the Swedish press. A study by the Economic Science and Communication Department at Karlstad University concluded that coverage from the press may have influenced the results of the 2007 festival.

In Sweden, schlager (a German word literally meaning a "hit") represents any song associated with the competition, from the jazz music featured heavily in the 1960s to entries such as Linda Bengtzing's in 2006. Christine Demsteader of The Local described Swedish schlager as "typically characterized by an annoyingly repetitive melody and trivial lyrics of little or no meaning". Jazz artists such as Monica Zetterlund and Östen Warnerbring won the event in the 1960s. ABBA, who won Eurovision in 1974, went on to be Sweden's most successful music export. The group influenced not only Melodifestivalen, but the entire Swedish mainstream music scene. In the 1980s, Bert Karlsson's Mariann Grammofon record label was responsible for the prevalence of "easy, memorable tunes". The early twenty-first century has seen more variety in the competition, such as Afro-dite's 2002
