The name has risen in popularity across the Anglosphere during the 2010s and 2020s. The character Ted Mosby on the popular American sitcom How I Met Your Mother, which aired from 2005 to 2014, might have influenced increased usage of the name. Modern parents more often use the diminutive Theo than Ted.^[2] Theodore was among the five most popular names for White newborn boys in the American state of Virginia in 2022.^[3] It has been among the ten most popular names for newborn boys nationally in the United States since 2021.^[4] It has been a similarly popular name for boys in Canada.^[5] The feminine form of Theodore is Theodora. In German, Theodore is the feminine form of Theodor.

Although similar to, and probably influenced by, the Germanic name Theodoric (and variants Theodoricus, Dietrich, Thierry, and others) have separate origins. It's also similar to Doris, another Greek origin given name. ^{[citation needed]}
