The definition is simple though. "A conglomerate is a multi-industry company". Google is in search, advertisement, video, music, hardware, productivity software, cloud, cars, etc. These are a substantial piece of the modern economy and if we aren't calling that "multi-industry", I am not sure th term has meaning.
