The marketers of Clearblue Advanced Pregnancy Test, a product that can tell you if you’re one-week, two-weeks, or three-plus weeks pregnant, asked a couple of D-list celebrities to tweet out their positive tests back in 2013. As Businessweek’s Jessica Grose reported, the maker of the test, Swiss Precision Diagnostics, has a 25% share of the at-home pregnancy-testing industry and is targeting its marketing efforts at Millennials. Grose quotes IbisWorld researcher Jocelyn Phillips as pointing to the high-tech aspects of Clearblue’s test, also noting that young women might be more willing to shell out more money for such technology — the digital version costs about $5 more than the boring old blue and pink line version.
