Abstract: This invention relates to computer implemented methods and systems for content mobilization, and in particular, methods and systems for mobilization of video, music, photos and other media, including processes for mobile search, mobile messaging, building a mobile content library, and combinations thereof. Content mobilization may be initiated by entry of search parameters or keywords and followed by retrieval of search results (e.g. videos, images, audio files) from online source(s). Upon selection of a content item by user, the process dynamically retrieves the media from online source. Further, the media file may be dynamically edited and then dynamically transcoded and sent to a mobile device.
