Many Mariann artists have entered Melodifestivalen, the Swedish qualifications for the Eurovision Song Contest. From 1978 to 2005, approximately 120 songs from Karlsson's record company competed, and 14 of these went on to represent Sweden in the Eurovision Song contest. Mariann artists include Herreys and Charlotte Perrelli, who went on to win the Eurovision Song Contest (1984 and 1999, respectively). In March 2005, Karlsson filled out an application for membership in the Liberal People's Party during a television interview. When the party immediately responded with criticism of him, calling the move a media stunt, he did not go through with his application. Karlsson was a judge in the first five seasons of the TV show "Talang" on TV4, the Swedish version of America's Got Talent, between 2007–2011. National Archive of Computerized Data on Aging  The National Archive of Computerized Data on Aging (NACDA) , located within ICPSR, is funded by the National Institute on Aging (NIA). NACDA's mission is to advance research on aging by helping researchers to profit from the under-exploited potential of a broad range of datasets. NACDA acquires and preserves data relevant to gerontological research, processing as needed to promote effective research use, disseminates them to researchers, and facilitates their use. By preserving and making available the largest library of electronic data on aging in the United States, NACDA offers opportunities for secondary analysis on major issues of scientific and policy relevance. A program within the Inter-university Consortium for Political and Social Research (ICPSR) at the University of Michigan. The NACDA collection consists of over sixteen hundred datasets relevant to gerontological research and represents the world's largest collection of publicly available research data on the aging lifecourse. The NACDA Program on Aging began over 30 years ago under the sponsorship of the United States Administration on Aging (AoA). At that time NACDA was seen as a novel experiment - neither the concept of a research archive devoted to aging issues nor the idea of making research data freely available to the public were well established.
