In Progress

Director trademarks not displayed

I noticed on a film's trivia page that this item was in the update form but not displayed on the trivia page:

DIRTRADE([link=nm0000005]): Theatre companies.

At first I edited it as follows, which didn't seem to help:

DIRTRADE([link=nm0000005]): [Theatre companies]

Then I added an explanation, and now the item is displayed:

DIRTRADE([link=nm0000005]): [theatre companies] Theatre and its staff featured.

https://www.imdb.com/title/tt0083922/trivia/

I found the same item in the update form for this title, where it is still not displayed and I haven't added the explanation:

DIRTRADE([link=nm0000005]): [theatre companies]

https://www.imdb.com/title/tt0087193/trivia/

The trivia guidelines say the explanation is optional:

DIRTRADE([link=nm######]): [trademark keyword]: optional explanation

DIRTRADE([link=nm######]): [flying]: the last scene of the film takes place on a hot air balloon

DIRTRADE([link=nm######]): [shooting on film, not digital]

I wonder if there are many other items that are not displayed.

Hi, Peter:

I wonder if there are many other items that are not displayed.

It's hard to tell from our end since now the contributor datasets (.tsv files) are generated a posteriori (based on the information that’s actually displayed on the page), unlike before 2018, when the old text archives (.list files) were generated directly from the core of the database (raw data), allowing for more in-depth analysis (e.g., to identify errors or inconsistencies like the one you’re reporting).

In fact, all those invisible items you're talking about don't appear in the latest title.trivia.tsv file, but they could indeed be tracked down in trivia.list with a bit of skill.

Obviously, the numbers have changed dramatically, but there's a curious surprise. Let's compare:

  • 19 Dec 2017 (latest available trivia.list): 865,762 trivia items, of which 1,714 are DIRTRADE entries.
  • 27 Apr 2026 (title.trivia.tsv 2026.04.27 17:28h):  2,096,104 trivia, of which 1,988 are DIRTRADE.

It is quite interesting that over the past 8 years, the number of trivia entries has increased by 142%, but the number of DIRTRADE entries has grown by only 16%, meaning that while they previously accounted for 0.2% of the total (20 in every 10,000 entries), they now represent only 9 in every 10,000 entries.

I can only think of two reasons for this change:

  • In recent years, IMDb has made it easier for anyone to submit information, and perhaps DIRTRADE-type entries are more typical of specialized film buffs who are familiar with a director's work.
  • The number of badly formatted DIRTRADE entries has increased, and as a result, the percentage of items made invisible by the system has risen.
  • As of 2018, prolific filmmaker and fellow contributor Mykola Yeriomin's director trademarks accounted for 539 of the 1,714 entries (31,4% of total), so I even began to speculate that the war in Ukraine might be having an impact on this decline. However, from 2018 onward 86 new entries have been added under his name (for a total of 625), which still constitute 31% of new DIRTRADE items (and happy news for everyone... 💪).

Focusing specifically on those entries that are hidden because they are formatted incorrectly, let’s analyze the 1,700 items up to 2018 (as I mentioned, anything "invisible" entry after that isn’t included in the text files), and to do so, we first need to remember the correct syntax for a DIRTRADE entry.

Here is the breakdown of the data:

  • Total DIRTRADE items: 1,714 items.
    • VISIBLE ITEMS (well formatted): 1,527 items (89.1%)
    • INVISIBLE ITEMS (badly formatted): 187 items (10.9%)   (a same entry can have several errors)

I haven't checked them all, but, to my surprise, a small number have since been corrected, so most of them are still stored (visible in edit mode), yet they are not displayed on their respective trivia pages.

Therefore, to answer Peter's question, an estimate that about 10% of the entries are hidden might be more or less accurate.

Cheers! 😊
