Why are there five bullet points after the phrase "Three things have led to the demise of the test card"?

Mentions that American broadcasters are switching off the NTSC broadcast by 2009. Should also mention UK analogue signal switch off? Popher 23:14, 3 May 2006 (UTC)

This article seems to be written by a Brit and as such lacks a certain objectiveness. I don't mean anything negative by this, simply that there seems to be an assumption that British culture is the same in America. It's nothing pervasive, just something I noticed. 72.49.117.53 20:28, 13 March 2007 (UTC)dethtoll

Are there enough references in popular culture to make a section for it? I can think of two. Saturday Night Live, I think, spoofed the popularity of Jerry Seinfeld's sitcom, with a report that NBC would be broadcasting a test pattern hosted by Mr. Seinfeld, and that it would be getting equally high ratings. I'm not sure I'm remembering it right.

Expecting Someone Taller by Tom Holt is a humorous sequel to Wagner's Ring Cycle. At the climax, when the old world ends and a new world is about to begin, bands of color appear in the sky. "What's that?" "That's the test card." 99.9.112.31 (talk) 19:32, 14 October 2010 (UTC)NotWillRiker

Test Card Wiki

Just wanted to let enthusiasts know there's a new wiki devoted to test cards at http://testcard.wikia.com/ -- please come help add articles and set up the structure of the wiki! Thanks — Catherine\^talk 03:01, 22 April 2008 (UTC)

"sine wave" test tone

About the undefined "sine wave" test tones in the article, my recollection is that (here in the U.S.) there were two standard "sine wave" audio test tones that commonly accompanying our test patterns.  The tones alternated while the pattern was transmitted.  One tone was 440 cps (440 Hertz), A above middle C in the musical scale.  I might be wrong, but I believe the alternate tone was 660 cps (660 Hertz), a perfect fifth above "C".  In the U.S., radio and television station broadcast engineers (technicians licensed by the U.S. Federal Communications Commission) used the two relatively low tones to set and record (log) television transmitters' peak audio modulation level, as required by F.C.C.'s broadcast rules and regulations.

• This information on the audio tone that accompanies the video signal should be on the main page.--Mark v1.0 (talk) 13:08, 1 February 2010 (UTC)
