What do you mean by "one organization"?
If you're referring to an organization that regulates all (or almost
all) utilities, Texas isn't the only state. Every state has some sort
of utility regulatory agency (although they go by variety of names:
http://tinyurl.com/2qx65y ). Indeed, Texas is an oddball in this
respect: the TPUC regulates all utilities except natural gas; the
Texas Railroad Commission regulates natural gas; and the Texas DOT
regulates railroads.
If you're referring to an organization that regulates landline
telephone service, again, Texas isn't the only state. Almost every
state regulatory agency (by whatever name) regulates landline service
(I say "almost" because there's probably an exception somewhere; I've
just never heard of one).
If you're referring to an organization that assigns area codes, no
state, not even Texas, does this. Area codes in the United States are
assigned by NANPA ( http://nanpa.com/ ), and implemented by the state
(or territorial) regulatory agency. In every state, including Texas,
the state agency determines the *method* of area code relief (overlay,
split, or boundary realignment), and it can *request* specific area
codes.[*] But NANPA makes the final decisions on code assignments.

Actually, the format was N,(2-8),X. No area code can have 9 as the
middle digit; these codes are reserved for some unspecified future use.

NANPA had probably assigned 361 to Texas as a relief code long before
the TPUC even held hearings.
When NANPA assigns an area code, it has to consider several
constraints:
- An area code can be used only once. A new area code can't conflict
with any other area code anywhere in the United States, Canada, Bermuda,
US territories in the Pacific, or a hodgepodge of geopolitical entities
in the Caribbean.
- An area code can't (or at least shouldn't) conflict with any central
office code within the area code; thus, for example, 573-573 would be
a prohibited combination. Consequently, when a new area code is
assigned, it must be selected from the list of presently-unassigned
central office codes. That list is likely to be short: if an area
code needs relief, it's already running out of central office codes.
(And yes, I'm aware of the 847-847 exception to this rule.)
- An area code can't conflict with any of several reserved
combinations: N11, N9X, NYY (second and third digits the same),
370-379, 456, 521-529, 555, 880-889, 950, 960-969.

If you apply all of these constraints to any given area-code relief
situation, you end up very few usable possibilities. In order to
avoid ending up with zero possibilities at some future date, NANPA has
established "Geographic Relief Codes" -- two or three codes held in
reserve for each state for possible future use. To ensure that these
codes remain available, they are never assigned as central office
codes within the state.
I suspect that 361 was one of these Geographic Relief Codes. I
wouldn't be surprised if it was assigned back when the 512/210 split
was under consideration.

NYC yes, Chicago no.
This issue invariably comes up in area code relief proceedings: if the
wireless (paging, cellular, and PCS) companies are using up all the
numbers, why not put them in their own "service-specific" area code?
The New York PSC adopted a service-specific overlay in New York City
in 1992 when 917 was overlaid on 212 and 718. The wireless companies
didn't like it because that "funny" area code put them at a
competitive disadvantage. Furthermore, reaching a 917 number from 212
or 718 required 11-digit dialing, while intra-area code numbers were
dialable with seven digits.
The next attempt to implement a service-specific overlay wound up in
the FCC's lap. In this case, Ameritech wanted to overlay 630 on 312
and 708 in the Chicago area. The wireless companies protested to the
FCC, asserting that service-specific overlays were not "competitively
neutral." The FCC eventually ruled that Ameritech could implement 630
as an all-services overlay or a split, but not as a service-specific
overlay.

If we're going to add any digits, I'd suggest adding a check digit to
prevent wrong numbers. Similar to UPC codes.

That sounds like another "service-specific" scheme. Furthermore, how
would a telco know what a given landline would be used for? Phone?
Answering machine? Fax? PC modem? Alarm system? TiVo? All of above?
If we're going to have any type of service-specific coding, I'd suggest
a code for coin phones.

Zenith (and Enterprise) were used throughout the country for
operator-assisted calls to businesses willing to accept charges. I
suspect that Zenith was chosen because it couldn't be dialed.

Are you sure? That totals eight digits. Source?

Well, I guess that's better than KRemlin.

Combinations in the form 58X were widely used as far back as the
1950s. In point: St. Louis (LUcas); Chicago (JUniper). Mark Cuccia's
post "Recommended 'EXchange' Names" (TD 25:118, 03/26/06) lists the
following 58X combinations: JUniper, JUno, JUstice, LUdlow, LUther.

Well, we exhausted the original 144 area codes in 1994, so we had to
adopt interchangeable area codes. Every area code introduced since
01/01/1995 is identical to a central office code in dozens of other
area codes.

Not necessarily. Some SxS exchanges used four-digit numbers (or four-
and 5-digit intermixed). In point: Ann Arbor. http://tinyurl.com/jtg3f

Once again: are you sure about eight-digit numbers? Source?

Neither was the second digit. Which is why N1X and N0X combinations
were not used for central office codes. Which (conveniently) is why
they were available in 1947 for use as area codes.

I don't follow that sentence.
[*] Many states have requested specific (vanity) area codes. Lexington,
home of the University of Kentucky, is in UKY. Knoxville, home of
University of Tennessee's Volunteers, is in VOL. In Florida, Daytona
Beach has FUN, Miami gets SUN, and Cape Canaveral does the 321 countdown.
Several Caribbean entities have commemorated themselves: Anguilla
(ANG), Antiqua (ANT), Bahamas (BHA), British Virgin Islands (BVI),
Grenada (GRE), Puerto Rico (PTR), St. Lucia (SLU), St. Vincent and the
Grenadines (SVG), and Trinidad and Tobago (TNT). [Thanks to Mark
Cuccia for this list.]
But Nevada couldn't get 777, so it had to settle for 775. Two cherries
and a lemon.
In some area codes, unintentional vanity equivalents have arisen. In
Chicago's northern suburbs, every VIP carries a BAG. Canada's northern
territories are at the TOP of the world. In Utah, 385 spells ... well,
I'll let you figure that out.
