In 1990 the first democratic local elections that took place marked a new period in the city's history. The economy of Katowice has been transforming from the heavy industry of steel and coal mines into "one of the most attractive investment areas for modern economy branches in Central Europe". Recently, the city's efficient infrastructure, rapid progress in the overall development and an increase in office space has made Katowice a popular venue for conducting business. The Katowice Expo Centre ("Katowickie Centrum Wystawiennicze") organises trade fairs or exhibitions and attracts investors from all over the world.
