ooVoo, a third party developer, is looking to bring video chat capabilities to the PlayStation 4 soon. The news was revealed by ooVoo themselves at CES 2015.

Now, I've never heard of ooVoo before, but it seems like an alternative or an "answer" to Skype. So, think of ooVoo appearing on the PS4 as that system's response to Skype being on the Xbox One.
