A few days ago, a number of German-language online articles were published that referred to this study (https://www.researchgate.net/publication/383536049_You_Like_Day-tuh_and_I_Like_Daa-tuh_Let's_Call_the_Whole_Thing_Off): "It seems similarly likely that the popular television show Star Trek: The Next Generation (original release 1987 – 1994) had
an impact on the American public: The show featured the character Lieutenant Commander Data, whose name was pronounced “day-tuh.” Sackett (2002, p. 130 – 131) reports that Commander Data’s name was originally pronounced “daa-tuh” prior to production, but was changed to “day-tuh” for the actual televised series."
