The launch of a new burger rarely triggers an industrywide reaction. Yet McDonald’s introduction of the Big Arch burger in early March quickly evolved into a viral marketing moment that pulled rivals into the spotlight. Burger King was among the first to respond, turning a simple taste test video into a new chapter in the long rivalry between the two global fast-food companies.
The episode illustrates how social media has reshaped competitive dynamics in the quick-service restaurant sector. Marketing campaigns that once unfolded through television commercials and billboards now play out through short-form video and brand personalities online. In this case, a CEO taste test and a rival’s playful jab generated millions of views and renewed attention to one of the industry’s oldest brand battles.
The Big Arch launch and the viral taste test moment
McDonald’s rolled out the Big Arch burger in the US as a new premium offering designed to expand its core burger lineup. The sandwich features two beef patties layered with white cheddar, lettuce, pickles and crispy onions, finished with a signature Big Arch sauce and served on a sesame and poppy seed bun.
The launch might have followed a conventional path if not for a video posted by McDonald’s CEO Chris Kempczinski. In the clip, the executive samples the burger on camera while discussing the product. The video was intended to showcase the new item and reinforce the company’s enthusiasm around the launch.
The clip quickly spread across social media platforms where viewers analyzed everything from the presentation to the CEO’s small bite of the burger. Memes and commentary appeared within hours, turning the video into a viral moment far beyond the brand’s initial marketing push.
For marketers, the reaction illustrated the unpredictable nature of modern product launches. Even carefully produced corporate content can take on a different life once it enters the fast-moving ecosystem of online commentary and humor.
Burger King moves quickly to capitalize on the moment
Burger King responded with a video of its own. The company released a clip featuring its US president, Tom Curtis, taking a large bite of the chain’s signature Whopper. The contrast with the earlier McDonald’s video was clear without being explicitly stated.
The moment was widely interpreted as a playful jab at McDonald’s and its viral taste test video. Social media users quickly linked the two clips, circulating them side by side across platforms and fueling further discussion about the rivalry between the brands.
Burger King has a long history of referencing competitors in its advertising. Over the years, the company has leaned into a challenger identity, often positioning its products as a more rebellious alternative to McDonald’s menu.
In this instance the strategy required little explanation. The humor and timing allowed the response to spread organically through online conversation, demonstrating how brands can insert themselves into trending moments with minimal production.
Wendy’s joins the conversation with its own burger video
The rivalry quickly expanded beyond two brands. Wendy’s entered the discussion after its president, Pete Suerken, shared a video showing himself preparing and eating one of the chain’s Baconator burgers.
In the clip, Suerken walks viewers through the ingredients before taking several bites of the burger while pairing it with fries and a Frosty. At one point, he jokes that the Frosty machine is working, a remark many viewers interpreted as a lighthearted reference to complaints about McDonald’s ice cream machines.
The video continued the pattern set by McDonald’s and Burger King executives, appearing on camera with their products. Online reactions compared how each executive approached the moment, from the hesitant bite in the original video to the exaggerated Whopper bite and Wendy’s more casual demonstration of its Baconator.
Why viral brand rivalry remains one of fast food’s strongest marketing tools
Competitive marketing has been part of the fast-food industry for decades. Chains frequently use comparison advertising, playful mockery and product challenges to capture consumer attention.
The digital environment has intensified this dynamic. Platforms such as TikTok, Instagram and X reward quick reactions and shareable content, allowing brands to participate in cultural moments almost immediately.
For Burger King, responding to the Big Arch video reinforced its challenger positioning while keeping the Whopper at the center of the conversation. For McDonald’s, the attention surrounding the original video still generated substantial visibility for its new menu item.
Moments like these often produce marketing value that exceeds the scale of the initial campaign. Viral clips can reach millions of viewers within hours, offering exposure that would otherwise require a significant advertising budget.
The episode highlights a shift toward more personality-driven brand communication. Executives, franchise leaders and social media teams increasingly appear on camera to promote products or comment on industry developments.
This approach humanizes large brands but also introduces unpredictability. Once content circulates online, audiences may reinterpret or parody it in ways brands cannot fully control.
At the same time, that unpredictability can become an asset. Viral discussion, even when humorous or critical, keeps a product at the center of public conversation. For large restaurant chains competing in a crowded market, sustained attention is often the most valuable outcome.
