Ayelet Noff, founder and CEO of SlicedBrand, has been building communications programs for technology brands in Israel, the U.S., and Europe since 2007, long enough by 2020 to have seen several category resets in public relations. Her 2021 predictions focused on six shifts already visible in Q4 2020: TikTok's move from experiment to primary channel, Apple's App Tracking Transparency rollout, the Substack turn in newsletter economics, altruistic brand ethos as a hiring and messaging category, journalist churn out of legacy media, and the shift from influencer marketing toward user-generated content. See also EPR's companion Q&A with Noff, published the same month, on how PR teams should navigate election-week news cycles.
Prediction 1: TikTok becomes a primary channel
Noff argued 2021 would be the year TikTok crossed from experiment to primary channel for consumer brands. The platform passed 100 million U.S. users through 2020, ad products matured through Q4, and the creator ecosystem hit a scale where brands could operate on TikTok the way they operated on Instagram. She expected consumer-brand budgets to shift meaningfully out of Instagram and Facebook toward TikTok through the year.
Prediction 2: Apple's ATT reshapes mobile advertising
Apple's App Tracking Transparency framework, delayed from the iOS 14 launch and scheduled for early 2021, would require apps to request permission before tracking users across other apps and websites. Noff predicted opt-in rates below 30%, a meaningful hit to Facebook's targeting and attribution infrastructure, and a rush toward first-party data infrastructure across the DTC category.
Prediction 3: Substack turns newsletters into a category
Substack passed one million paid subscriptions in late 2020. Noff predicted the platform would become the reference case for a broader industry shift: journalists leaving legacy media for direct-audience platforms, brands treating newsletter sponsorship as a primary channel rather than a one-off, and the newsletter format maturing into a stable owned-media category.
Prediction 4: Altruistic brand ethos as a category
Noff argued 2020 forced every consumer-facing brand to take a public position on values: health, workforce, community, racial justice, sustainability. She expected the differentiation between brands that funded action and brands that only ran the campaign to become explicit in 2021, with talent recruiting and purchasing decisions both correlating more strongly with brand ethos than in any prior year.
Prediction 5: Journalist churn out of legacy media accelerates
Related to Prediction 3 but distinct. Noff expected journalist departures from major legacy outlets to accelerate through 2021, driven by Substack economics, editorial-independence disputes, and the ability to build direct-to-reader businesses at scale for the first time. She recommended PR teams map their target-media list at the individual-journalist level, not the outlet level.
Noff predicted the influencer-marketing category would peak in 2021 as brands realized that UGC, authentic customer content curated and amplified, outperforms paid influencer content on trust and conversion metrics. She expected the category to persist but the resource allocation to shift toward UGC infrastructure and away from traditional influencer negotiations.
The wild card: Clubhouse
Noff flagged Clubhouse, the invite-only audio platform that launched in April 2020 and grew quickly through Q4, as the single highest-uncertainty call in her forecast: it could become a top-tier channel through 2021, or plateau into a niche tactic. She recommended brands build a presence and test formats without shifting primary spend.
How these predictions held up
TikTok: correct, and understated. TikTok did not just become a primary consumer-brand channel in 2021, it became the platform that now functions as the discovery layer of the internet for entertainment, beauty, fashion, food, and travel discovery. See EPR's TikTok hub for the full scale of what that turned into by 2026.
Apple's ATT: correct. The framework rolled out in April 2021. Opt-in rates landed even lower than the 30% ceiling Noff projected, and the hit to Meta's targeting and attribution infrastructure was significant enough that the company cited it directly in subsequent earnings calls. The first-party data rush she predicted became standard DTC operating practice.
Substack: partially correct. Substack did mature into a durable newsletter category and did pull real bylines out of legacy media. What Noff underestimated was the shape of the shift: the bigger story became creator-led paid subscriptions rather than brands treating newsletter sponsorship as a primary ad channel.
Altruistic brand ethos: correct near-term, less durable than predicted. 2021 did see the differentiation Noff described. By 2023 to 2024, several major brands scaled back overt values-messaging following consumer backlash episodes, and the category proved more cyclical than the one-way shift she forecast.
Journalist churn: correct. The migration out of legacy newsrooms toward Substack and independent platforms accelerated significantly through 2021 to 2023, matching Noff's prediction closely.
UGC over influencer marketing: directionally correct, overstated. Influencer marketing did not peak and decline the way Noff predicted. It professionalized instead, adjusting into the credibility-driven, category-authority model EPR documents in its post-bubble influencer marketing coverage. UGC grew alongside influencer spend rather than replacing it.
Clubhouse: correct. The platform's momentum collapsed after 2021 and it became a niche product, exactly the outcome Noff flagged as the more likely of her two scenarios.

What is Apple's App Tracking Transparency?
A framework announced with iOS 14 and rolled out in April 2021 that requires apps to request user permission before tracking activity across other apps and websites. It reduced the effectiveness of mobile ad targeting on iOS and pushed the industry toward first-party data infrastructure.
Did TikTok actually become a primary brand channel?
Yes, and beyond what was predicted in 2020. By 2026 TikTok functions as the discovery layer for entertainment, beauty, food, fashion, and travel, not simply a primary paid-media channel.
What is UGC and why does it matter?
User-generated content: authentic customer photos, videos, reviews, and social posts. It grew alongside influencer marketing rather than replacing it, contrary to the 2020 prediction that it would overtake the category.
What happened to Clubhouse?
The invite-only audio platform lost momentum after 2021 and became a niche product, confirming the more cautious of the two outcomes Noff flagged as possible in her original prediction.
