Definition
2K17 is a way of writing the year 2017 that is common online, in which the digit zero is replaced with the letter K. The letter comes from the Latin "kilo," meaning a thousand, so the construction reads as "two thousand seventeen" with an unusual emphasis on how it's written.
The spelling was used on both the English-language and Russian-language internet. It worked as a short marker of time that was easily recognized in captions, usernames, and headlines.
Similar substitutions of digits with letters appeared in other online date notations as well, so the spelling "2K17" can be seen as one specific case of a broader tradition of visual wordplay with numbers in internet culture.
Origin of the spelling
The spelling arose as an imitation of the titles of sports simulators from the company 2K Sports. The NBA 2K series came out annually, and its installments carried the year's digits in the title: for example, NBA 2K17 was released in 2016 and was developed by the studio Visual Concepts. The "2K17" notation emerged from these titles.
The trend, as the catalog notes, was borrowed specifically from the titles of computer games. The search confirmed the release of NBA 2K17 and the existence of games in the series with years in their titles, but did not yield a source documenting the first appearance of the spelling online.
Connection to 2K Sports games
Games from 2K Sports and its series, such as NBA 2K and WWE 2K, came out with the year's digits, so the construction "2K17" was perceived as a recognizable marker. Users could associate it with a specific product, but often simply used it as the year.
Over time, the spelling moved beyond the specific game. It began to be used in a joking context, where the letter K had nothing to do with games and served merely as a playful device.
Given that the 2K series released games almost every year, this way of denoting the year could also have been perceived by users as a reference to the very regularity of new installments coming out, rather than to one specific product alone.
Spread and meaning
The spelling appeared in captions, usernames, hashtags, and headlines, especially at the end of 2016 and through 2017. It was often used as a marker of time, and sometimes as a joke about the spelling of the year itself.
Such constructions are typical of internet culture, where short and visually unusual signs quickly take on a life of their own. That is why "2K17" is often found outside the original context of games.

The illustration attached to the article is the text "2K17" in purple on a black background. The image matches the catalog entry and requires no caveats. No game logo is shown in it, so the connection to 2K Sports is apparent only from the article's text.
The exact date of the first use of this spelling has not been established. The search confirmed only the release of the NBA 2K17 installment and the fact that 2K Sports released games with the year's digits in their titles.
