I want to know the answer to the following question:
On what film was videoconferencing widely used?
All the background I'm provided with is that "For example, for the 2013 award-winning animated film Frozen, Burbank-based Walt Disney Animation Studios hired the New York City-based husband-and-wife songwriting team of Robert Lopez and Kristen Anderson-Lopez to write the songs, which required two-hour-long transcontinental videoconferences nearly every weekday for about 14 months.". Is that enough to answer the question?
Answer: yes
