A number of Dublin's traditional industries, such as food processing, textile manufacturing, brewing, and distilling have gradually declined, although Guinness has been brewed at the St. James's Gate Brewery since 1759. Economic improvements in the 1990s attracted a number of global pharmaceutical, information and communications technology companies to the city and Greater Dublin Area. Companies such as Microsoft, Google, Amazon, eBay, PayPal, Yahoo!, Facebook, Twitter, Accenture, TikTok and Pfizer now have European headquarters and/or operational bases in the city, with several located in enterprise clusters like the Digital Hub and Silicon Docks. The presence of these companies has driven economic expansion in the city and led to Dublin sometimes being referred to as the "Tech Capital of Europe".
