1999: Birth at NTT DoCoMo
The story of emoji begins with Shigetaka KuritaShigetaka Kurita
ศิลปินชาวญี่ปุ่นที่สร้างชุดอิโมจิชุดแรก — การออกแบบ 176 ชิ้นขนาด 12x12 พิกเซล — สำหรับบริการอินเทอร์เน็ตมือถือ i-mode ของ NTT DoCoMo ในปี 1999, a young engineer at NTT DoCoMo in Japan. Working on the i-modei-mode
แพลตฟอร์มอินเทอร์เน็ตมือถือของ NTT DoCoMo ที่เปิดตัวในปี 1999 ซึ่งเป็นที่ที่อิโมจิชุดแรกถูกสร้างขึ้นเพื่อพัฒนาการสื่อสารทางข้อความ mobile internet service, Kurita's team needed a way to express emotions and convey information in the constraints of early mobile messaging — where screen space was limited and text-only communication felt flat.
Kurita designed 176 emoji, each a 12×12 pixel grid. He drew inspiration from manga expressions, weather symbols, and traffic signs. These tiny icons covered weather (☀️ ☁️ ☂️), emotions (😊 😢), and everyday objects (📱 ✉️). His original set is now in the permanent collection of New York's Museum of Modern Art.
2000-2009: The Japanese Carrier Wars
DoCoMo's emoji were a hit, so rival carriers created their own sets:
- SoftBank (then J-Phone/Vodafone) created a colorful set with 3D-style designs
- au/KDDI developed yet another incompatible set
The problem: sending an emoji from DoCoMo to SoftBank might show a completely different symbol — or nothing at all. This fragmentation was frustrating for Japanese users who expected emoji to work everywhere.
2007-2009: Google and Apple Take Notice
As smartphones went global, two companies recognized emoji's potential:
Google proposed adding emoji to Unicode in 2007, submitting a formal proposal with Apple. Engineers from both companies worked to map the three Japanese carrier emoji sets into a unified encoding.
Apple quietly added emoji support to iPhone in 2008 — but only for the Japanese market (iPhone OS 2.2). A hidden emoji keyboard existed in the system, and tech-savvy users worldwide found ways to enable it, creating grassroots demand.
2010: Unicode 6.0 — Emoji Go Global
In October 2010, Unicode 6.0 officially incorporated 722 emoji. This was the watershed moment: emoji were now a global standard, not a Japanese curiosity.
The initial set included the familiar smileys, animals, food, weather, and symbols — but notably lacked diversity in human representation.
2011-2014: Platform Adoption
The years after standardization saw rapid adoption:
- Apple enabled the emoji keyboard globally in iOS 5 (2011)
- Android added native emoji support in Android 4.1 (2012)
- Windows added color emoji in Windows 8.1 (2013)
- Twitter created TwemojiTwemoji

Each platform designed its own visual style, leading to the cross-platform rendering differences we still see today.
2015: Emoji 1.0 and Skin Tones
Emoji 1.0 brought a transformative addition: skin tone modifiers based on the Fitzpatrick dermatological scale. Five modifier characters could be appended to human emoji, allowing users to select from six skin tones (including the default yellow).
This update also formalized the emoji versioning system, making it easier to track when specific emoji were added.
2016: The ZWJ Explosion
Emoji 4.0 was a landmark release, adding over 2,000 new emoji through ZWJ (Zero Width JoinerZero Width Joiner (ZWJ)
อักขระ Unicode ที่มองไม่เห็น (U+200D) ใช้เพื่อเชื่อมอิโมจิหลายตัวเข้าเป็นอิโมจิรวม เช่น การรวมคนและวัตถุเป็นอิโมจิอาชีพ) sequences. Gendered professions — woman firefighter 👩🚒, man cook 👨🍳, and dozens more — each with skin tone variants, massively expanded representation.
This version demonstrated the power of ZWJ sequences: combining existing emoji with an invisible joiner character to create new meanings without allocating new code points.
2019: Accessibility Emoji
Emoji 12.0 responded to calls for disability representation by adding: wheelchair users (🧑🦽), people with prosthetic limbs (🦿🦾), hearing aids (🦻), guide dogs (🦮), and the white cane (🧑🦯). These emoji were the result of a proposal by Apple advocating for better representation.
2020-Present: Maturity and Refinement
Recent years have seen the emoji set mature:
- Emoji 13.0 (2020): Trans flag 🏳️⚧️, ninja 🥷, pinched fingers 🤌
- Emoji 14.0 (2021): Melting face 🫠, handshake with skin tones 🫱🏻🫲🏿
- Emoji 15.0 (2022): Shaking face 🫨, moose 🫎, pink heart 🩷
- Emoji 15.1 (2023): Head shaking, phoenix 🐦🔥, lime 🍋🟩
- Emoji 16.0 (2024): Just 3 new emoji, signaling the set's maturity

What's Next?
The era of adding hundreds of emoji per year is over. The Unicode ConsortiumUnicode Consortium
องค์กรไม่แสวงหากำไรที่พัฒนาและดูแลมาตรฐาน Unicode รวมถึงกระบวนการเพิ่มอิโมจิใหม่ has become increasingly selective, raising the bar for new proposals. Future emoji additions will likely be small, focused, and fill specific representation gaps rather than broad categories.

ฟีเจอร์ของ Google ที่ให้ผู้ใช้รวมอิโมจิสองตัวเป็นสติกเกอร์มิกซ์อย่างสร้างสรรค์ มีให้ใช้ใน Gboard และ Google Search mashups, AR emoji avatars, and ever-more-expressive sticker packs show that pictographic communication is still growing — just beyond the Unicode standard.
