Aibo is a friendly robotic dog whose personality and behavior evolves over time. It can recognize its owner's face, detect smiles and words of praise, and learn new tricks. And of course, it loves to be petted.

Sony unveiled the original Aibo in 1999. The first generation (models ERS-110 and ERS-111) sold about 65,000 units. Second-generation models were released in 2001, 2002, and 2003. Third generation models arrived in late 2003 (model ERS-7), and the ERS-7M3 model, released in 2005, was the latest. The company would eventually sell more than 150,000 units until it decided to discontinue the robot in 2006 amid protests from Aibo fans. In 2017, Sony announced it was launching a brand-new version of Aibo, completely redesigned with more advanced mechatronics and AI. Model ERS-1000, priced at 198,000 yen (about US $1,750), was introduced to the Japanese market in early 2018. In August 2018, Sony announced that, after selling 20,000 new Aibos to Japanese consumers, it was making the robot canine available also in the United States. A bundle, including the robot, toys, and charger, retailed for $2,900. Also part of the package is a three-year cloud subscription plan, required for users to explore all features of the Aibo app. In 2024, Aibo celebrated it's 25th anniversary.
