Does instant film is still needed? While it can make people see immediately of what they shoot, nowadays all digital cameras do that. That's why Polaroid ceased their film production by the end of the year.
Stated on this site: http://thelede.blogs.nytimes.com/2008/02/08/polaroid-abandons-instant-photography/, that any 3rd party could have it's license to make the film thus continuing the instant film legacy.
Still, it's not the death of instant film since Fujifilm still keeping their Instax line on full production. Nevertheless the word 'instant film' is so unseparable with polaroid in mind.
