"Realtime" is unfortunately an overloaded term, as even the Wikipedia article shows. Realtime in the context of the web applications is closest to what is considered a "soft" realtime application. Wikipedia defines this as: The usefulness of a result degrades after its deadline, thereby degrading the system's quality of service. In the context of the web, it refers to some type of data (text, voice or video) broadcasting/synchronization. Chatrooms and multiplayer gaming are some examples of this type of software. A lot of people include newsfeeds and notifications in this definition but those can be delayed arbitrarily without much degradation of QoS.
