2015 Fix
The breakthrough gene-editing tool CRISPR-Cas9 was named the "Breakthrough of the Year" by Science magazine. It opened new, controversial possibilities for treating genetic diseases.
After the misstep of Windows 8, Microsoft launched Windows 10 on July 29, 2015. The new operating system was designed to unify the user experience across PCs, tablets, and phones (though the phone part would ultimately fail). Key features included the return of the Start Menu (now with customizable Live Tiles), the new Edge browser to replace Internet Explorer, and the voice assistant Cortana. Perhaps most controversially, Microsoft offered the upgrade as a free download for Windows 7 and 8 users – a move that drove rapid adoption (over 100 million devices in its first month) but also drew criticism for aggressive “nagware” tactics. Windows 10 would go on to become the dominant desktop OS for the rest of the decade.
In July 2015, NASA’s New Horizons spacecraft completed a historic flyby of Pluto. Operating billions of miles away from Earth, the probe captured high-resolution imagery of Pluto's icy mountains and its vast, heart-shaped nitrogen glacier. This data permanently updated humanity's understanding of the outer solar system.
A poorly lit photograph of a bandage dress went viral worldwide in February. The internet split over whether the garment was blue and black or white and gold, sparking global scientific debates on human color perception.

The extremist group expanded its reach, executing coordinated terror attacks worldwide. The November attacks in Paris killed 130 people at the Bataclan theatre and other venues, prompting global security lockdowns. Social Progress and Domestic Shifts Windows 10 would go on to become the
In February 2015, the internet was utterly divided over a photo of a dress, debating whether it was blue-and-black or white-and-gold. It became a masterclass in viral, social media-driven pop culture.
Pop music in 2015 was defined by a few monumental releases. Adele returned from a four-year hiatus with “Hello,” the lead single from her album 25 . The music video broke the Vevo record for most views in 24 hours (27.7 million). The song dominated charts worldwide and became one of the best-selling digital singles of all time. Meanwhile, Drake’s “Hotline Bling” – with its infectious beat and instantly meme-able music video (featuring Drake’s awkward dad-dancing) – became an inescapable cultural phenomenon. Other defining tracks included Mark Ronson’s “Uptown Funk” (feat. Bruno Mars), The Weeknd’s “Can’t Feel My Face,” and Justin Bieber’s comeback singles “What Do You Mean?” and “Sorry.”
On June 26, 2015, the U.S. Supreme Court handed down its ruling in Obergefell v. Hodges . In a 5–4 decision, the court held that the Fourteenth Amendment requires all states to license and recognize marriages between same-sex couples. Justice Anthony Kennedy wrote for the majority: “No union is more profound than marriage, for it embodies the highest ideals of love, fidelity, devotion, sacrifice, and family.” The decision effectively legalized same-sex marriage nationwide, legal in all 50 states. Celebrations erupted from the White House (lit in rainbow colors) to Stonewall Inn in New York. It was a historic civil rights victory, and one of the defining moments of 2015.
The year was also defined by significant social progress and shifts in public consciousness.
In December, 195 nations adopted the first-ever universal, legally binding global climate deal at COP21. This historic pact committed the world to limiting global warming to well below 2 degrees Celsius.
