I am trying to fill in the bracketed parts of the following sentence:

According to [ ], approximately [xx] million analog TVs have been sold
worldwide since (sometime between 1990 and 1995).

For the sake of definition, an "analog TV" is a TV that uses analog
display technology and is typically a cathode ray tube (CRT)
television.  An analog TV is definitely NOT a plasma or an LCD TV. 
The research companies that deal with the TV markets understand the
difference between analog TVs and digital TVs.

The Consumer Electronics Association provides this data for the United
States, but not worldwide...I need worldwide.  I also need the data
source to consent to being quoted in a published document.

According to U.S. Representative Edward J. Markey (D-MA), the ranking
Democrat and part of the House Subcommittee on Telecommunications and
the Internet...
At the Hearing on Digital TV Transition, March 10, 2005:

"... in 2004, the television industry sold 31 million TV sets. Just
over a million of them included digital tuners to
receive digital TV signals. That means that last year, approximately
30 million TV sets were sold that had
only analog TV reception capability. Let me repeat that ? last year 30
million analog TV sets were sold."
