I want to know the answer to the following question:
What is the videoconferencing product that both IBM and PictureTel worked on?
All the background I'm provided with is that "While videoconferencing technology was initially used primarily within internal corporate communication networks, one of the first community service usages of the technology started in 1992 through a unique partnership with PictureTel and IBM Corporations which at the time were promoting a jointly developed desktop based videoconferencing product known as the PCS/1.". Is that enough to answer the question?
Answer: yes
