Systems and methods for delivering social network updates from popular entities to receiver devices via broadcast or multicast networks obtain updates from highly popular entities. Updates may be assembled by a server crawling social network sites. To enable selective reception, the obtained updates may be broadcast/multicast according to a schedule that is communicated to receiver devices in advance, such as a catalog file. Receiver devices receive the catalog file and use the included information to selectively receive updates that are relevant to a user of the receiver device. Updates received from broadcasts or multicasts are cached in memory of the receiver device. When a user requests to access a particular social network entity on the receiver device, that request may be satisfied by accessing social network updates cached on the receiver device. Broadcasting and/or multicasting highly popular social network updates may relieve burdens on unicast networks. |
