A number of original Star Trek stories appeared in UK publications.
Detailed information on Star Trek comic strips was researched by Rich
Handley. Most of this information was published in Star Trek
Communicator and is duplicated here with his generous permission.
Subsequently, Shaqui Le Vesconte, a collector of UK Star Trek strips,
provided additional information. Any mistakes generated by the data-meld
I have attempted are entirely my own.

Paramount commissioned ongoing comic strips based on Star Trek from 1969
to 1973, published in Britain by City Magazines in the titles Joe 90:
Top Secret, TV21 and Joe 90, Valiant and TV21, and TV Comic. The artwork
on these British strips was provided by such talents as Frank Bellamy,
Harry F. Lindfield, Mike Noble, John Stokes, Roland Turner, Jim Baikie,
John Canning, H. Jones, Carlos Pino, and Alan Willow. Writers for most
of the strips remain unknown.

In January 1965, Alan Fennell, in cooperation with British sci-fi
puppeteer Gerry Anderson, began publishing a weekly newspaper for City
Magazines entitled TV21, with strips based on such Anderson projects as
Stingray, Supercar, Fireball XL5, Captain Scarlet and Thunderbirds.
Immensely popular in Britain, the magazine lasted 242 issues until
February 15, 1969, when declining sales brought about numerous changes.
The first was the magazine's title, which became Joe 90: Top Secret,
while another was the contents. Gone were many of the original series,
with non-Anderson stories such as Star Trek and Land of the Giants added
to the lot.

Joe 90 lasted 34 issues before enduring another major change. Renamed
TV21 & Joe 90 to recapture departed fans, the magazine again added and
dropped some of its titles. Star Trek survived the merger and became
the most popular title in the magazine, ironic not only in that few
Anderson stories remained in what began as an Anderson vehicle, but also
because televised Star Trek had been canceled that same year.  By issue
34, the "& Joe 90" in the magazine's title was dropped, TV21 having
re-established itself among British readers. However, proving how
easily history repeats itself, TV21 changed yet again after 105 issues,
merging with Valiant in 1971. Valiant and TV21 ran until October 16,
1976, but the Star Trek strip was dropped after 118 issues, coming to a
final rest on December 29, 1973.

In addition to the weekly magazines, additional original material
appeared in the 1969 Joe 90 hardcover annual, the Valiant 1972 Summer
Special, the 1971-1973 TV21 Hardcover Annuals and the 1978-1978 TV Comic
Hardcover Annuals. An original Frank Bellamy Star Trek strip also
appeared in the June 27, 1970 edition of the magazine Radio Times. All
told, nearly five years of weekly Star Trek strips were published during
the British run. Bellamy and Alan Willow produced covers for the series,
which alternated between Star Trek and other titles until such painted
illustrations were dropped as of issue 42 to allow an increase from two
to three pages of Star Trek material per issue. Though sometimes
inaccurate in terms of technical details, much of the artwork created
for the series was very well-rendered.

Trek Magazine, a fanzine published in the 1970s by Walter Irwin and G.B.
Love, reprinted a few of the Valiant strips, but the vast majority of
this material has never been reprinted in the United States. The
complete series of Star Trek strips published in 258 issues, annuals and
magazines amounts to nearly 600 pages of material including all Star
Trek-related covers. It's unlikely that these strips will ever be
reprinted.
