The UK's economy used to be based on manufacturing. However, since the 1960s, manufacturing has declined, and tertiary and quaternary industries have grown. In 2017, these industries employed 83% of the UK's workforce -- and this proportion is increasing. Important industries include: Services -- e.g. retail and entertainment. Retail employs about 4 million people in the UK. Information technology -- over 670,000 people work in IT, for companies like IBM and Microsoft. Finance -- the UK, and especially the City of London, is home to many global financial institutions. Some, like HSBC, have their global headquarters in the UK. Research -- research and development (R&D) is increasing in the UK, making use of the UK's skilled university graduates. In 2016, over £33 billion was spent on R&D in the UK.
