"Sirius Satellite Radio Inc. said on Wednesday it is planning a children's video service for cars in 2006, a year later than it had expected, using software from Microsoft Corp. Sirius, which provides subscription based satellite radio services for a monthly fee, said last year it would offer video services by mid-2005. Spokesman Jim Collins said timing depended on automakers rather than Sirius' capability. "All of our partners have expressed an interest." said Collins. "The timing of the service is dependent on when our automotive partners are ready." He did not disclose specific agreements but noted that Ford Motor Co. had demonstrated Sirius' video technology in some Lincoln Mercury models at car shows. Collins said video was not part of Ford's existing agreement to offer Sirius in up to 1 million cars in two years beginning this summer."I guess streaming Sponge Bob to the kids in the back of the minivan is a good thing for most parents. Score another victory for WMV though. Microsoft should work with the automakers to make them see that satellite video is important to consumers and help enable them to use this service.
