Words to know

gatekeeper
A person or system that decides what reaches an audience.
ranking system
Software that orders and selects content for each user's feed, often called the algorithm.
context collapse
When usually separate audiences all see the same post.
imagined audience
The audience a creator pictures while making a text.
disclosure
A clear statement that content is sponsored or that the creator has a material connection to a brand.
ethos
The credibility and trustworthiness of a speaker or creator.

Remember from Grade 11

In Grade 11 (ENG3U) you explained how complex texts have layered purposes (surface, business and value), how they create an implied viewer, and how mode of address (direct or indirect) positions an audience. You also met algorithmic personalization: on many platforms, two people see different versions of the media world.

Grade 12 asks you to explain, with insight, how complex and challenging texts are built for purposes and audiences. In 2026 that means one more step: on platforms, a text is not just aimed at people. It is also aimed at a ranking system that decides which people will ever see it.

Hook: the parka review

An invented creator in Sudbury, @NorthernShift, posts a 45-second video: Is a $400 parka worth it at minus 30? The first two seconds show her face in a blizzard, eyelashes frosted. A caption reads I wore it for 30 days so you don't have to. At three seconds, a small label: Paid partnership. The video ends: Full test in my profile. What should I review next?

Who is this video for? Her followers? Strangers in Winnipeg? The parka company? The app? The answer is all of them, and every choice in the video serves at least one of them.

Five audiences of a platform text

  1. Core audience: people who follow and trust the creator. They come for her voice and honesty.
  2. Algorithmic strangers: people the feed shows the video to because their behaviour predicts they'll watch. They have never heard of her and decide in about a second whether to keep watching.
  3. The sponsor: a company that paid for the video and wants exposure and credibility from a trusted voice.
  4. The platform: a business that earns money when people stay on the app, because it sells their attention to advertisers.
  5. The ranking system: the software that measures early reactions (watch time, replays, shares, comments) and decides whether to show the video to more people. Creators often call this the algorithm. It acts as a first audience and a gatekeeper.

A gatekeeper decides what reaches an audience. In the 20th century, gatekeepers were mostly editors and producers. Today, ranking systems share that role with them.

A platform media text is designed for several audiences at once: people who follow the creator, strangers the feed finds, a sponsor, the platform itself, and the ranking system that decides who sees it next. Each has a different purpose.

Purposes stack up

Each audience brings a purpose, and a complex text often serves several at once:

  • Creator: inform viewers, express a personality, build a community, earn income.
  • Sponsor: sell parkas, borrow the creator's trust (her ethos).
  • Platform: keep viewers watching and scrolling.

Some purposes support each other (an honest review builds trust, which helps the sponsor). Some pull against each other (a sponsor wants praise; viewers want honesty). Grade 12 analysis names these tensions and explains how the text manages them. In Canada, the Competition Bureau expects influencers to disclose material connections such as payment or free products clearly, so the Paid partnership label is also a response to a rule.

Context collapse

On platforms, audiences that used to be separate (friends, family, teachers, employers, strangers) can all see the same post. Researchers Alice Marwick and danah boyd called this context collapse. It explains why creators write for an imagined audience and why a post can be read very differently from how its maker intended.

Context collapse: one post, audiences that used to be separateONE POSTmade for friendsclose friendsfamilyclassmatesa future employertotal strangersThe joke that works for close friends may read very differently to the others.
Context collapse (a term from researchers Alice Marwick and danah boyd): on social platforms one post can reach audiences that would normally hear different versions of us. Creators manage this by imagining a broad audience or by narrowing who can see a post.

What makes a text complex?

The Grade 12 expectation names complex and challenging texts. Signs of complexity:

  • Multiple purposes and audiences at once, sometimes in tension.
  • Hybrid form: a review that is also an ad, a diary and a community post.
  • Intertextuality: references to other videos, memes, trends or genres that only some viewers recognize.
  • Multimodality: meaning built from image, speech, on-screen text, music and interface features (labels, links, comments) together.
  • Ambiguity: the purpose or stance is not stated, so the audience must infer it.

How to explain design for purpose and audience

Use this chain: choice, then evidence, then audience, then purpose. The first two seconds show her frosted face in a blizzard (choice and evidence) to stop algorithmic strangers from scrolling (audience) so the video earns watch time and gets shown more widely (purpose).

Worked example

Let's analyze the parka review

Explain how three design choices in the invented @NorthernShift video serve its different audiences and purposes, and name one tension.

  1. Choice 1: the cold-open hook. The video opens on her frosted face in a blizzard, not on the parka. Audience: algorithmic strangers who decide in a second. Purpose: hold attention so the ranking system reads strong early watch time and shows it to more people.
  2. Choice 2: the 30-day claim. I wore it for 30 days so you don't have to signals effort and honesty. Audience: core followers and strangers. Purpose: build ethos, which the sponsor is paying to borrow.
  3. Choice 3: the closing question. What should I review next? invites comments. Audiences: the community and the ranking system (comments are an engagement signal). Purpose: build community and boost distribution at the same time.
  4. Disclosure. The Paid partnership label at three seconds answers the Competition Bureau's expectation of clear disclosure and protects her credibility with followers.
  5. Tension. The sponsor wants a positive review; followers want honesty. She manages this by including one honest criticism (the hood blocks your side view), which makes her praise more believable to viewers and still useful to the sponsor.

The video is designed for five audiences with stacked purposes. The hook serves strangers and the ranking system; the 30-day claim builds ethos for followers and the sponsor; the closing question serves community and distribution. The main tension (sponsor praise versus viewer trust) is managed with disclosure and one honest criticism.

Four questions for platform texts

For any platform text ask: Who sees this first? Who decides who sees it next? Who paid? Who profits from attention? Your answers usually reveal purposes the text never states.

Just for fun

Creators sometimes say they are making content for the algorithm. The algorithm has never once bought a parka, laughed at a joke or shovelled a driveway. It is the strangest audience in history: it watches everything and feels nothing.

Hands-on activity

Audience map of a real feed text

You need: a phone, tablet or computer with a grown-up's OK, paper and a pencil.

  1. Choose one short video or post you saw this week from a creator, brand or news outlet.
  2. Draw the five-audience map from this lesson. In each box, write what that audience wants from the text.
  3. Find three design choices (the first seconds, on-screen text, a call to action, music, a label, a link). For each, write one chain sentence: choice, evidence, audience, purpose.
  4. Name one tension between purposes and explain how the text handles it.
  5. Check: is any sponsorship disclosed? Where, and how clearly?

What to look for: all five audiences considered, three chain sentences tied to specific evidence, and a tension that is explained, not just named.

For parents and teachers

What this lesson teaches: explaining how complex media texts are created for particular purposes and audiences (expectation 1.1), extended to platform media where a ranking system acts as a first audience and gatekeeper. It introduces context collapse (Marwick and boyd). The creator and parka video are invented.

How to help at home:

  • Watch one short video together and ask: Who is this for? Who paid? Who decides who sees it?
  • Point out disclosure labels (ad, paid partnership) and talk about whether they are clear.
  • Ask your teen to explain one design choice using the chain choice, evidence, audience, purpose.

Common difficulties:

  • Naming audiences without evidence. Every audience claim should point to something in the text.
  • One purpose only. Push for at least two purposes and one tension.
  • **Treating the algorithm as magic.** It is software that responds to measured human behaviour; it is explained more fully in the lesson on recommendation systems.
