Actually they were developed for analog computers. The op in opamp stands for operational because they were able to perform various mathematical operations such as addition, subtraction, integration, etc.
Most people think of an Op Amp as a chip. But they are made in many forms from potted modules made from trimmed discrete components to power OP Amps in TO3/220 cases that can drive speakers directly to several hundrfed watts.
Check this mother of a power opamp out:
Can operate off +/-75 volt rails and deliver +/-30 amps. :)
