If you grew up thinking Hydrox was the knockoff of Oreo, you are not alone. In reality, Hydrox came first in 1908 and Oreo followed in 1912, yet Oreo completely took over the chocolate sandwich cookie world. That got me wondering how often the copycat ends up eclipsing the original. As it turns out, the Hydrox vs. Oreo story is not unique at all.

In Short

• Hydrox really did come before Oreo, but Oreo won the popularity war and basically rewrote history.
• The same pattern shows up with breakfast pastries, candy, toys, tech, search engines, and even video games.
• In most cases, the later product wins because of better marketing, better timing, or a more polished user experience, not because the original idea was bad.

Hydrox vs. Oreo: The Backwards Cookie Story

Let us start with the cookie that inspired this whole topic.

• Hydrox debuts first. Hydrox cookies were introduced in 1908 as a chocolate sandwich cookie with a creme filling.
• Oreo arrives later. Nabisco launched Oreo in 1912, four years after Hydrox, positioned as a very similar product that looked and ate like the original.
• Perception flips. Oreo eventually dominated store shelves and marketing, to the point that many people now assume Hydrox is the cheap imitation instead of the original cookie.

This is a recurring pattern: the first one through the wall does the pioneering work, and a later competitor comes in with better branding or distribution and ends up owning the category.

Pop Tarts vs. Country Squares: The Toaster Pastry Race

Toaster pastries are another good example of “second to market, first in mind.”

• Post moves first. Post developed a foil wrapped toaster pastry called Country Squares and publicly talked about it before it was ready for shelves.
• Kellogg reacts faster. Kellogg rushed out a competing product, test marketed it, and launched it nationwide as Pop Tarts in 1964. Early shipments sold out quickly, and Pop Tarts became a huge hit.
• Result. Country Squares are mostly a trivia answer now, while Pop Tarts turned into a decades long breakfast brand that never really went away.

M&M’s vs. Earlier Candy Coated Chocolate

Chocolate coated in a hard shell was not completely new when M&M’s showed up in 1941. There were earlier sugar coated chocolates and similar ideas, including British products that inspired the concept. What made M&M’s explode in popularity was less about inventing the idea from scratch and more about how it was packaged and marketed:

• Compact, shareable packaging.
• Military contracts during World War II that put M&M’s into soldiers’ rations.
• Strong branding and mascots over time.

Earlier versions faded into the background, while M&M’s became the standard candy coated chocolate worldwide.

Froot Loops vs. Earlier Fruity Cereals

Fruity breakfast cereal was not completely invented by Kellogg, but Froot Loops is the brand most people think of today. General Mills’ Trix predates Froot Loops, yet Froot Loops managed to carve out huge name recognition of its own and arguably became the more iconic “colored ring” cereal in a lot of markets.

Transformers vs. The Original Toy Lines

Transformers look like a smash hit original idea, but the robots in disguise concept started somewhere else.

• Japanese originals. In Japan, Takara sold transforming toys under lines like Microman and Diaclone, starting in 1980. These already featured vehicles and robots that transformed, often piloted by small figures.
• Rebrand for the West. Hasbro licensed these toy molds, merged lines, added new names and storylines, and launched them in North America in 1984 as Transformers.
• Result. Transformers became a massive worldwide media franchise with cartoons, comics, and movies, while most people outside collectors have never heard of Diaclone or Microman.

iPod vs. Early MP3 Players

If you remember the iPod era, it can feel like Apple invented portable digital music. That was not the case.

• Early MP3 players. Devices like the SaeHan MPMan and the Diamond Rio PMP300 were being sold in the late 1990s. The Rio PMP300 in particular was the first commercially successful MP3 player and even ended up in a major court case with the recording industry.
• iPod arrives later. Apple launched the first iPod in 2001 as a hard drive based player with a simple click wheel interface and tight integration with iTunes.
• Why the “knockoff” won. The iPod was not first, but it was easy to use, held a lot of songs for the time, and came with aggressive marketing. It quickly became the default term for an MP3 player, while those earlier devices faded into tech history.

Google vs. The First Search Engines

Google also fits this pattern. It was not the first search engine, or even close. The web already had Archie, AltaVista, Lycos, Yahoo, and others trying to make sense of the internet.

• Google launches in 1998. Larry Page and Sergey Brin turned their PageRank research project into a company and a live search engine that ranked sites based on links, not just simple keyword matching.
• Cleaner and faster. At a time when rival portals were getting cluttered, Google kept a plain homepage and focused on speed and relevance.
• Result. Even though it came later, Google quickly became the dominant way to search the web and eventually turned earlier giants like AltaVista into footnotes.

Fortnite vs. PUBG (And The Battle Royale Boom)

In gaming, the battle royale craze gives a modern example of the “copy beats the creator” pattern.

• PUBG arrives first. PlayerUnknown’s Battlegrounds (PUBG) brought the battle royale format to the mainstream in 2017, building on earlier mods and survival games.
• Fortnite pivots. Epic Games had already released Fortnite as a co-op survival game, but in September 2017 they added a free battle royale mode that very clearly followed PUBG’s format.
• Fortnite explodes. Thanks to the free to play model, constant updates, cross platform releases, and a more approachable style, Fortnite became a cultural phenomenon, even while PUBG remained popular.

PUBG did a lot of the pioneering work, but Fortnite is the game most non gamers think of when they hear “battle royale.”

When Branding Beats Being First

There are countless smaller examples that follow the same script:

• Swiffer turned dust mops and electrostatic cloths into a successful brand, even though similar cleaning tools existed before.
• Q tips made “cotton swabs” so famous that people use the brand name generically.
• Febreze became the go to odor eliminating spray, overshadowing earlier neutralizer products.

In each case, the later product did not have to invent the entire idea from scratch. It only had to be easier to find, easier to understand, or more appealing to use.

Why The “Knockoff” Often Wins

From these examples, a few common themes show up:

• Better marketing. Oreo and Pop Tarts pushed harder with branding and advertising than their earlier rivals.
• Distribution and shelf space. The product that is easier to find often wins, even if it is not the oldest.
• Refinement instead of invention. Google did not invent search, and the iPod did not invent portable digital music. They refined what was already there into something smoother and more user friendly.
• Timing. A later product can arrive at a moment when technology, culture, or the market is finally ready to embrace the idea.

Hydrox vs. Oreo is just one example of a much larger story. Being first is impressive, but history is full of “knockoffs” that ended up defining the category.
