Fuji and Kodak are doing lots of advertising for their film products. Other members have already given you several very good examples, see the postings above. Like the instagram pages of Kodak. They are also active on Facebook:

Fujifilm is also active on instagram:

They are doing there also regularly their "Film Friday" competition in which you can win free film.
Fujifilm has also started a film photography webpage for starters in film photography:
https://www.ishootfujifilm.com/
But that is their smallest marketing project: For their instax film products you will find dozens of Fujifilm social media pages because all local Fujifilm operations run their own marketing, perfectly fitted for the special needs of the local markets: In some countries they are using TV commercials for their numerous Instax film products (e.g. in Asia). Here in Germany they are advertising in online photo magazines and photo print magazines. And they have opened their "Fujifilm Wondershop Stores" in many countries, selling their photo products in these brick-and-mortar stores. These stores are doing local marketing.
Social media is currently the most effective way for marketing. We can confirm that from our own experience. Therefore we have increased our activities there, too:

'Fujifilm has invested like no other film manufacturer: They have made their instax instant film line to the most successful photo products at all in the photo market."
Neither Kodak nor Fujifilm are going away from film. Not at all. Just the opposite is right: Both are investing in film. In new production capacities and products.
Kodak is currently investing in new converting capacities (we have a whole thread here in this subforum about that topic, please have a look at it). And they are investing in re-introduced film products, like TMZ and Ektachrome. They are also investing in new labs for cinema film.
Fujifilm has invested like no other film manufacturer: They have made their instax instant film line to the most successful photo products at all in the photo market.
With this product line they have blown all digital manufacturers "out of the water" concerning sales volume: In their last fiscal year they have produced more than 10 million instax cameras. So they have produced more film cameras than Canon, Nikon, Sony, Olympus, Panasonic, Fujifilm, Pentax, Sigma, Hasselblad, Phase One have produced together digital ILC cameras! Sales of ILCs of all these digital camera manufacturers were only 8,2 million cameras.
And whereas digital camera sales are massively declining, instax sales are increasing.
Of course not only the sales of instax cameras, but also instax film. Dozens of millions of instax film packs are sold p.a. Fujifilm is running their lines in 3 shifts per day to keep up with demand.
Furthermore Fujifilm is bringing Acros back, also a big investment and a clear commitment to film.
