The range includes a new type of device called the Chromebit, which looks like an oversized memory stick, and turns monitors and TVs into computers when plugged into their HDMI ports.

The Chromebits will be made by the Taiwanese manufacturer Asus.

The tech firm also revealed the cheapest Chromebook laptops to date, costing $149 (£101).

The move is likely to intensify competition with Microsoft.

The announcements came less than a day after Microsoft revealed plans to sell a new entry-level tablet-laptop hybrid of its own.

Its Surface 3 costs more -$499, and £419 in the UK for the basic model - but provides access to a wider range of software made for the Windows platform.
