Gothic

Gothic is a style of a sanserif typeface. It is more commonly called a Grotesque or Grotesk.

Grotesque refers to the set of sans-serif fonts produced around 1815. Gothic is another name for Grotesque. Caslon is considered the first Gothic.

Blackletter is often called Gothic also, though not technically the right word for that style of a typeface. If you are curious, please do a search for these terms.

They choose a Gothic typeface because they wanted their work to look clean and modern.
