Which company introduced the Kindle e-reader in 2007?

Amazon introduced the Kindle e-reader in 2007.

Amazon launched the first Kindle on November 19, 2007. The device used an electronic-ink display and connected wirelessly to Amazon's digital bookstore, allowing readers to buy and download books without connecting to a computer.

The Kindle helped Amazon expand beyond physical retail into digital publishing and consumer hardware. Amazon later added features such as touchscreen displays, adjustable lighting, waterproof models, and access to subscription services including Kindle Unlimited.

The Kindle is not the same as a tablet such as Amazon's Fire tablet. Kindle e-readers are primarily designed for reading and use electronic ink, which generally offers longer battery life and a paper-like display. The product also reinforced Amazon's broader ecosystem of devices, content, and online services.
