Rodrigo asked me a great question. He asked, "When we talk about a band, we sometimes say 'they' and sometimes say 'it.' When I write emails at work and I refer to companies, I don't know whether they are singular or plural. Do I say 'Coca Cola has to make the delivery' or 'Coca Cola have to make the delivery?'"
Company names and band names are "collective nouns." Collective nouns are nouns that describe a family, a company, a band, or other group. In U.S. English, we use singular verbs with collective nouns that describe a group acting as a group rather than as individuals. We use singular verbs with company names. Coca Cola has to deliver the report today. Microsoft owns Skype. Facebook is under investigation in a number of countries. We use singular verbs with company names because companies act as a unit.
In the United States, we treat musical groups a bit differently. We generally use singular verbs with groups whose names are singular nouns and plural verbs with groups whose names are plural nouns. Cold Play is playing in New York in March. Chicago was one of my favorite groups in the '70's. The Beatles were a fantastic group. Black Eyed Peas have won numerous awards.
So, while the accountants from Coca Cola have to deliver the report, Coca Cola has to deliver the report.
Have a great afternoon!
