A Tech tabloid is a type of news media that mainly concentrates on technology news: science, IT, semiconductors, telecoms and related issues, but also takes on a less formal and more humorous approach than traditional technology publications such as EE Times or EDN.
They are professional in nature, though, rather than community-based technology news sites such as Digg or Slashdot.
The tabloid tag does not apply to the paper format, as many of these publications are web-based only, such as The Inquirer and The Register.
The sarcastic, iconoclastic and skeptic tones of these publications is often more akin to publication such as Private Eye, which would not usually be labelled a tabloid, than to the Page Three tabloid such as The Sun and the Daily Star.
Both the Register and the Inquirer do generally have red banners at the top of their home pages.
