When I first got into photography in 1997, only the news agencies and papers with the biggest budgets were using digital. There were a huge number of films available. Kodak, Fujifilm, Agfa, Konica, and Scotch all made color film for the US market.
Fuji's product lineup honestly was not that much different than theirs today. They had a few more specialist products, such as duplicating film and interneg film, as well as a 1600 speed Provia, but other than these, it was very similar to today.
Kodak, on the other hand, sells a fraction of the types of color film they did 13 years ago.
This was Kodak's color film lineup around the middle of 1997:

There were other more obscure color films not mentioned also, such as VR 200, VR400, etc, etc...
And some films, such as Gold 1600, Lumiere 50, Ektachrome 64x, Kodachrome 40, etc. had existed during the earlier 1990s, but had been discontinued prior to 1997. I was very young at the time and didn't get to use many of the films listed in this post.
B&W was very similar to today, except that Technical Pan, Verichrome Pan, HIE, and and an orthochromatic film existed. (And TMY was on its first version). Even in 1997, your choices were basically Plus-X, Tri-X, 3 speeds of T-Max, or a chromogenic ISO 400 film.
