Sony's AIBO was a $2,500 robotic dog that 150,000 people bought — and Sony killed in 2006

Sony's AIBO (Artificial Intelligence Robot) was unveiled in 1999 as one of the most advanced consumer robots ever created. The ERS-110 model could walk, recognize voices, respond to commands, express emotions, and learn from its environment. It was a showcase of Sony's engineering prowess — artificial intelligence, advanced robotics, and entertainment technology combined in a single product. The first batch of 5,000 units sold out in 20 minutes in Japan and the US.

The problem was the price. At $2,500, AIBO was a toy for millionaires. Sony sold about 150,000 units across four generations (ERS-110, ERS-210, ERS-220, ERS-7) over seven years — impressive for a $2,500 robot, but negligible for a company Sony's size. The project was a technological success and a commercial niche. AIBO earned a cult following, but it never approached the scale needed to justify its enormous R&D investment.

In January 2006, newly appointed CEO Howard Stringer announced the end of AIBO production as part of a sweeping restructuring. The project was killed not because it was a failure, but because Sony could no longer afford to fund curiosity-driven research. Sony ended repair service in 2014, sparking a movement of owners who hacked their AIBOs to keep them alive. In 2018, Sony revived the brand with a new model, proving the concept had always been viable — just not at the price the original required.

Sony killed AIBO in 2006 restructuring, despite 150,000 units sold, because the price limited it to a niche.

At $2,500, AIBO was too expensive for a mass market — Sony's R&D produced a technical marvel that only the wealthy could afford, limiting total sales to ~150,000 units

Sony's 2006 restructuring forced CEO Stringer to cut unprofitable divisions — AIBO had a passionate user base but not the revenue to survive a corporate cost-cutting drive

AIBO was a research project sold as a consumer product — the engineering outpaced the commercial reality, and the price gap was never closed

A $2,500 robot dog that 150,000 people love is a cult success, not a business. Sony's R&D could build the future — but it could not sell it at a price the future could afford.

AIBO owners organized repair communities and hacked their dogs to keep them running. Sony revived the brand in 2018 with the ERS-1000 at approximately $3,000. The new model is still sold, but remains a luxury product. The original AIBOs from 1999 are now collectibles, with some selling for more than their original price. The case is taught as an example of the gap between technological capability and commercial viability — Sony could build the robot dog, but it could not make the dog affordable.
