This is because according to Microsoft, Skype will now support TripAdvisor and StubHub add-ins. According to Microsoft, “The TripAdvisor add-in for Skype lets you tap into the world’s largest travel site from your group chat to help plan a trip. With the new TripAdvisor add-in, you can instantly share information with your group about where to stay, what to do, and where to eat with friends.”
The same is applied to StubHub where the add-in will help streamline the entire process where users can find tickets for upcoming events, buy them, and share the details of events with those in the group. All of this is done without the user having to leave Skype or switch to a browser which can be inefficient and you might miss messages in between.
So far the new add-ins are available on Skype for Mac, Skype for mobile, and according to Microsoft, are in the process of being rolled out onto Skype for Windows 10 as well.
