The cities along the M4 corridor are home to a number of high-profile blue-chip companies such as Admiral Insurance, Legal & General and the Welsh-based Principality Building Society. A large number of telephone call centres are located in the region and in particular in the Valleys area. Merthyr Tydfil is home to the principal UK call centre for German mobile telephone company, T-Mobile. Many jobs are also provided in small-scale and family businesses. It is clear from anecdotal personal contacts, apart from official figures, that the new industries have so far failed to cope with the task of providing stable employment for the large number of employable people resident in the area.
