Wi-Fi on University Buses
On a long bus ride home recently to visit family, I was able to do online research and complete assignments because the bus was equipped with an Internet connection. This got me thinking: wouldn’t it be great if we had Wi-Fi on our university buses? We could use that time more productively to do assignments that often require being connected to the Internet. I imagine this could be expensive, so how could it be paid for? Well, sometimes empty buses run all day along certain unpopular routes on campus. Reducing bus service along these routes that don’t get a lot of use could save money to fund the upgrade.

Joint Ventures
Companies often want to offer new services to customers to increase profits. However, sometimes an individual company lacks a particular skill necessary to offer a different kind of service. So it may combine its existing skills or capabilities with those of another company to offer a new service together through what is known as a joint venture . The two companies create a third, separate company in a project or venture that joins their individual areas of expertise. The two original companies continue to operate independently at the same time that they run the new company together and share its profits.
Explain how the example from the lecture illustrates the concept of a joint venture.
