Mains powered clocks with an induction motor became popular in the 1930s but were still being made in the 1970s before battery powered quartz clocks replaced them. Smiths and Metamec appear to be the most common manufacturers. Mantlepiece and bedside clocks were more common in the 1930s but wall clocks were more common in the 1970s and tended to be used in commercial buildings more than homes.
The ubiquity of electric clocks in the mid 20th century resulted in the creation of a secure plug and socket combination, where the plug was held in place with a screw to prevent it from being casually pulled out, called a clock connector. They are still sold today although they are more commonly used with alarms rather than clocks.
