The acceleration mechanisms and observational features of jets in active galactic nuclei, and the recent research progresses on these topics are reviewed in this paper. The size of the region in which the jet is magnetically accelerated is estimated. The different magnetically driven jet models are presented, and the formation and maintenance of the ordered magnetic field configuration of the disks are discussed. The observational evidence on the disk-jet connection in active galactic nuclei and the correlation between the central black holes and their radio properties are summarized.
