120 film should still be here for the next decade, if the hobbyist community remains strong. When we Boomers die off, it may be harder for the film companies to justify the existence of it, but who knows?
Digital is inherently a superior medium for all its sharing advantages, but film has a look that many find appealing. The experience of using a very expensive recording medium in a completely manual camera can be pleasantly challenging, as well.
Go to the big online dealers bhphotovideo.com and adorama.com and search for 120 films. I just did… I am impressed! B&H lists 54 120 films, and Adorama lists 44. Some are brands I never heard of before the fall of Kodak and its reincarnation as Kodak Alaris.
