It's not just Adobe that's alter­ing its plans when it comes to brows­er plu­g­ins designed to play back rich web media — Microsoft's join­ing in too. New releas­es of Sil­verlight, Red­mond's big com­peti­tor to Flash Play­er, are report­ed­ly going to be aban­doned after the launch of Sil­verlight 5, expect­ed later this month. This infor­ma­tion comes from mul­ti­ple sources cited by the usu­al­ly well-informed Mary Jo Foley. They don't know how long Microsoft will main­tain sup­port for Sil­verlight 5 or if there'll be any ser­vice packs, but it does seem like the com­pa­ny will be switch­ing its oper­a­tional focus to other areas and halt­ing active devel­op­ment of Sil­verlight.
