Game Show Network (also known as GSN) is an American digital cable and satellite television channel dedicated to games shows and reality shows.
The font used for the logo of the TV channel is probably Gotham Black. Designed by Tobias Frere Jones, Gotham is a typeface inspired by the architectural signage seen in the New York City. You can view more details about it on Typography.com.
Update: The network dropped the GSN branding in 2018, reverted its name back to Game Show Network, and introduced a new logo to coincide with the branding. The new logo features stacked lines using Flama Semi Bold Cond and Gotham Ultra.
