The Numbers That Mattered
Marques Brownlee is arguably the most influential tech reviewer on the planet. His negative review of the Humane AI Pin became a cultural moment. Companies send him products months before launch. When he sold his Tesla Cybertruck and kept his Rivian instead, Elon Musk unfollowed him on X and Tesla cut off all communication — that's the level of industry weight his opinions carry [3]. So when Brownlee announced Panels in September 2024 — a curated wallpaper app born from the single most-Googled question about him ("where does MKBHD get his wallpapers?") — it seemed like a slam dunk. Real demand, massive built-in audience, a product that aligned perfectly with his brand. It wasn't a slam dunk. It was a case study in why building products is nothing like reviewing them. According to app intelligence firm Appfigures, Panels accumulated approximately 900,000 lifetime downloads across iOS and Android. Users collectively downloaded over 2 million wallpapers. Those engagement numbers sound respectable until you look at the revenue: roughly $95,000 in total consumer spending over 15 months. By November 2025, the app was generating 3,000 downloads and $500 in monthly revenue — numbers so small it couldn't rank on U.S. app store charts [1]. On December 1, 2025, Brownlee posted an unlisted YouTube video announcing the shutdown. Panels went offline on December 31. The code was open-sourced under Apache 2.0 in January 2026. All user data was deleted. Annual subscribers got refunds. It was, by all accounts, a clean exit. But the story of how it got there is more instructive than the ending.
