Teletext in the UK played host to two popular gaming sections before it’s closure, Digitiser and GameCentral.
Here are links to some articles & websites about them (more will be added as we find them):

note: The name Teletext is used in reference to the company of that name that ran teletext services on ITV and Channel 4, not “teletext” as sometimes used as a generic term for TV based information delivery.
