NEW YORK (

TheStreet

) -- On Jan. 22, Conan O'Brien finished his abbreviated run on

The Tonight Show

with his biggest audience turnout ever.

O'Brien averaged 5.3 million viewers in his final week, handily beating chief rival, David Letterman, who could only manage 3.9 million viewers.

The Tonight Show

also averaged ratings of 2.4 among viewers aged 18 to 49 in its final week, exceeding the kick-off week when O'Brien took over while Letterman fell to a 0.9 rating. O'Brien's final night drew a whopping 10.3 million viewers who tuned in to watch the late night comedian sign-off.

O'Brien left

GE's

(GE) - Get Report

NBC with a

severance package of $45 million

for himself and his staff, even though he was only on the show for 11 months. With O'Brien's departure, Jay Leno will return as host of

The Tonight Show

.

But you already knew all of that. You also presumably knew -- unless you were trapped underneath something heavy for the last month -- that Leno's own weeknight show,

The Jay Leno Show

, was canceled due to poor ratings and complaints from NBC's TV affiliates about the audience being delivered to their key 11 p.m. local news slot. And that NBC now plans to fill the void left by the cancellation of

The Jay Leno Show

with new scripted programming. And that the upcoming Winter Olympics will air on NBC and give the network a chance to promote its new lineup for prime-time weeknights. And that Leno will return to host

The Tonight Show

starting on March 1st.

What you presumably

don't

know -- because there is no legitimate way to know it just yet -- is who, ultimately, ended up benefiting most from the whole sordid little fiasco?

Rumors have surfaced that Fox, owned by

News Corp.

(NWSA) - Get Report

, is interested in hiring Conan O'Brien and giving him a new talk show. If such a move were to a occur, this would reunite Conan with the network that gave him one of his first breaks in writing for

The Simpsons

. So Fox might be a winner.

CBS's

(CBS) - Get Report

David Letterman, meanwhile, strongly benefited from the scandal.

Tonight Show

ratings slid after O'Brien picked up the helm, and Letterman claimed the #1 spot in the time slot.

NBC's move last fall to install O'Brien as the new host of

The Tonight Show

fulfilled a promise made years ago for him to succeed Leno. The gamble to placate Leno by giving him his own new show -- and then his old one back -- has clearly cost the company and angered its TV affiliates, but it's arguably turned out well for Leno (if one can ignore the damage to his reputation).

Readers of

TheStreet

, who do you think has won the most (or lost the least) from this debacle? Or is this one fight in which everyone loses?
