MTV and VH1 still have a (very) limited text service, which just consists of schedules, which I suppose is handy for the remaining analogue cable viewers without access to an
EPG.
Elsewhere, text still exists on: Paramount, Men and Motors, S4C, Travel Channel, TCM, Eurosport, At The Races, Extreme Sports, Racing UK, all EMAP channels, BBC Parliament, CNBC, CNN, Nickelodeon, Sony TV Asia, Zee TV...
Several of the UKTV channels have a BBC "Ceefax has ceased" page.
