In the year 2006, DV presented two trends: hard disk and DVD digital camcorders gradually replaced tape digital camcorders. We can see that Sony launched its own hard-disk digital camcorder this year and also reduced its promotional investment in tape machines. Currently, only Sony and JVC have a rich range of hard-disk DV products in the market. Canon and Panasonic, apart from tape machines, have been actively promoting their DVD digital camcorders. At the same time, Panasonic has added the 3CCD element to its memory card and DVD digital camcorders, making non-tape machines more competitive. The younger brother Samsung also focused on DVD digital camcorders in this year's promotion. All manufacturers are sending out a clear message: they plan to gradually exit the production and sales of tape machines. The reason is very simple. What drives them to gradually abandon tape machines is profit. DVD, hard disk, and other new storage media digital camcorders can bring them greater profits.
