Michael C. from Brooklyn asked whether social media should be capitalized in a sentence like this: I enjoy the social media era and the platforms that support it.
Michael's question was a little tricky because I know the names of real eras are capitalized, but I wasn't sure about the names of made up eras. The AP Stylebook calls for capitalizing the names of "widely recognized" eras and the Chicago Manual of Style recommends capitalizing "formal" eras. Based on that advice, I believe Michael should not capitalize social media since it isn't a well-known, established geological era or historical period.
· The Roaring Twenties
· The Great Depression
· The Paleozoic era
· The social media era
Although I don’t believe it’s required, I would also be tempted to hyphenate social media since it is acting as a compound modifier before the word "era." The hyphen would make it clear you mean one thing—social media, which comprises services such as Twitter and Facebook—instead of a media era that is also social, which could mean journalists who attend a lot of parties.
· I enjoy the social-media era.
If our time becomes widely and formally known as the Social Media era in the same way the 1920s are now commonly known as the Roaring Twenties, then social media would be capitalized you wouldn’t have to worry about a hyphen because the meaning would be clear..
