Today Sardinia is phasing in as an EU region, with a diversified economy focused on tourism and the tertiary sector. The economic efforts of the last twenty years have reduced the handicap of insularity, especially in the fields of low-cost air travel and advanced information technology. For example, the CRS4 (Center for Advanced Studies, Research and Development in Sardinia) developed the second European website and 1st in Italy in 1991 and webmail in 1995. CRS4 allowed several telecommunication companies and internet service providers based on the island to flourish, such as Videonline in 1994, Tiscali in 1998 and Andala Umts in 1999.
