Back in April we noted that Bloomberg TV would be shaking up its daytime lineup after the departure of Margaret Brennan. Now we have a date for the new lineup: tomorrow, Monday June 18th.

What are the changes? A refresher:

A simulcast of Tom Keene‘s radio program “Surveillance” which airs from 6-8amET replacing “Inside Track” which was hosted by Erik Schatzker and Stephanie Ruhle…

Betty Liu will continue to anchor “In the Loop” from 8-10amET. Then, Schatzker and Ruhle will host a new show at 10am, replacing Brennan’s “In Business.”

We have more details now: Keene’s show will actually be an all-new show across TV, radio and digital, not just a simulcast of his existing radio show. In addition Bloomberg is launching a new noon show called “Lunch Money.”

Margaret Brennan, who has been with Bloomberg TV for nearly three years, is leaving the network, TVNewser has learned. Brennan joined Bloomberg from CNBC in 2009. Brennan’s departure, described as mutual, comes as the network plans changes to its morning lineup later this Spring.

Andrew Morse, head of U.S. TV for Bloomberg, says the changes are a continuation of Bloomberg’s “evolution into a digital, multi-platform news organization.” The changes have included a round of staff cuts as well as the posting of new positions, last month.

The programming shifts include a simulcast of Tom Keene‘s radio program “Surveillance” which airs from 6-8amET replacing “Inside Track” which was hosted by Erik Schatzker and Stephanie Ruhle.

“It’s not just doing TV on the radio,” Morse tells TVNewser, “but a true multi-media program.” The show will stream on Bloomberg.com and on the Bloomberg TV+ and Radio+ tablet apps. Keene will be joined by Sara Eisen, Scarlet Fu and Ken Prewitt.

Betty Liu will continue to anchor “In the Loop” from 8-10amET. Then, Schatzker and Ruhle will host a new show at 10am, replacing Brennan’s “In Business.”

In a Media Beat interview last summer, Brennan told us about her decision to leave CNBC for Bloomberg, and also hinted at a true passion: international reporting. Brennan’s final day hosting “In Business” is this Friday.

Keene’s NoonET program goes away and will be replaced by a what Morse calls a “high-profile ensemble cast” who will be assessing the market at Midday.

Business Insider has published a list of “The 101 Finance People You Have to Follow on Twitter,” and all three business networks are represented.

From Fox Business Network, senior correspondent Charlie Gasparino was on the list.

Senior web editor John Carney, senior stocks commentator Herb Greenberg and assignment desk manager Ryan Ruggiero are the CNBCers on the list.

There are also three Bloomberg TV personalities on it: economics editor Linda Yueh, “Bloomberg Surveillance” host Tom Keene and markets reporter Sara Eisen.

Bloomberg News editor-at-large Tom Keene opens up to New York magazine this week about his diet: the “healthy and then less-than healthy” options in the Bloomberg TV pantry, what restaurant he sits at to write his blog and how to make the perfect cocktail. The “Surveillance Midday” anchor, who also co-hosts the morning show on Bloomberg radio, also talks about how difficult it is to get a good meal in while trying to deliver the news:

[Radio co-host] Ken Prewitt and I do the show, and I have breakfast during the nine o’clock hour. A classic kind of Winston Churchill breakfast: scrambled eggs, sausage, English muffin toasted twice, home fries. And I eat about half that because I’m on live. So, I can be talking about Euro, Yen, or the president’s economic policy, and I got a sausage in my mouth. The major goal of power breakfast is to not spill scrambled eggs on Ken Prewitt.

After a day of Saturday specials on the cablers, the networks are gearing up for the Asian markets opening later today and the opening of Wall Street tomorrow following Friday’s S&P downgrade of the U.S. CNN’s special coverage continues tonight with a 9pmET special hosted by Christine Romans. Fox Business will produce a 2-hour special tonight at 9pmET hosted by Gerri Willis. Also, at 8pmET Bloomberg Television presents a two-hour live report anchored by Tom Keene and Adam Johnson.

CNBC’s also got a special on at 8pmET called “Markets in Turmoil.” As part of it, CNBC’s Chief Washington Correspondent John Harwood will speak with Treasury Secretary Timothy Geithner who announced today he’s staying with the Obama Administration through the election.

This morning on “Meet the Press” former Fed Chairman Alan Greenspan said, “What I think the S&P thing did was to hit a nerve that there’s something basically bad going on and it’s hit the self esteem of the United States. The psyche. And it’s having a much profounder effect than I conceived could happen, because the economics of what they’re talking about is very clear.”

The news of CNBC anchor Mark Haines‘ death has been reverberating through the TV news business, and a number of other cable news channels took time out of their programming to pay tribute.

On Fox News Channel, former CNBC anchor Martha MacCallum said of Haines on “America’s Newsroom”: “He will be missed by so many in this business, he was one of the pioneers of the financial business news coverage, and a great market reporter, who worked at the stock exchange for many years and we will miss him.”

On CNBC competitor Fox Business Network, Stuart Varney reported the news at 10 AM, and had Nicole Petallides get the reaction from the New York Stock Exchange floor:

Bloomberg is a big name on Wall Street, and on days like today when the market is the story of the day, it enters the spotlight even more.

“This is an issue that is going to affect everyone going forward,” Bloomberg TV (U.S.) managing editor John Meehan tells TVNewser. “We have the opportunity to really expand the audience and invite other viewers who wouldn’t typically see us.”

One of the ways Bloomberg aims to accomplish that is its strong global presence. “Bloomberg news has more than 2000 reporters,” says Meehan. “We have a small army covering this particular issue from every angle you can imagine.”

Bloomberg, which was live, and is live, every Sunday night with feeds from other countries, spent even more time this weekend with the Lehman story breaking. Dispatching a team to the Fed for coverage all weekend, Bloomberg was feeling ready this morning. “We had people in place to follow what was a very fluid situation,” said Meehan.

Tonight, Bloomberg airs a special, “Reshaping Wall Street,” at 6pmET, anchored by Betty Liu. “Money and Politics” at 9pmET will cover the opening of the Asian markets and the latest Wall Street news. At 10pmET, Tom Keene anchors “Night Talk” and interviews John Ryding, chief economist at RDQ Economics.

Meehan says Bloomberg TV’s goal is to help those watching. “Viewers want to know when this is going to be over,” he said.
