The current era of logo design began in the 1870s[citation needed] with the first abstract logo, the Bass red triangle. As of 2014 many corporations, products, brands, services, agencies and other entities use an ideogram (sign, icon) or an emblem (symbol) or a combination of sign and emblem as a logo. As a result, only a few of the thousands of ideograms in circulation are recognizable without a name. An effective logo may consist of both an ideogram and the company name (logotype) to emphasize the name over the graphic, and employ a unique design via the use of letters, colors, and additional graphic elements.
