Remember the last time Andrew Breitbart was on MSNBC? His fiery exchange with David Shuster ended up in a lot of shouting and not a lot of discussing.

Well he was back on today with Dylan Ratigan – and Breitbart tells us he introduced the world to a whole new Andrew.

In the 16 months since we launched Mediaite, there have been certain topics that we as a site (and me, in particular) have taken a major, sometimes obsessive, interest in.

As I head out today, I want to connect what I see as the common thread between some of my favorite topics to cover.

Diamond Dallas Page left the WCW/WWF world in 2002, but has kept busy by starting YRG Fitness (formerly Yoga for Regular Guys) and acted in several movies.

But there’s somewhere else you may start seeing DDP – reality TV. Here’s more from my interview with the wrestling superstar.

Sarah Palin‘s next bestseller, America By Heart, isn’t out until Tuesday, but Palin haters and the lamestream media are already leaking portions of it.

One fun nugget? Palin enjoys movies like Knocked Up and Juno – films featuring unplanned pregnancies, and decisions not to have an abortion.

Bill Carter took his publicity tour for The War For Late Night to late night last night – as a guest on Jimmy Kimmel‘s ABC show.

With two weeks since the book’s release, Carter could talk about the reactions he’s gotten from people who have read it – like Jeff Zucker and Jay Leno.

It was clear who James Carville supported during the 2008 Democratic primary, squarely for Sen. Hillary Clinton over Sen. Barack Obama.

So how much has changed? After telling an old campaign joke, Carville went on CNN to reiterate “I’m not sorry and I don’t apologize.”

Diamond Dallas Page is a three-time world champion in the WCW and wrestled for several years in the WWF, but his post-wrestling career has really taken off – and in an unusual way.

Shepard Smith was busy talking about one of his favorite new topics, junk-touching, when suddenly a car chase interrupted the conversation. That’s right – the greatest Shepard Smith transition of all time took place this afternoon.

Glenn Beck‘s reign as arguably the most successful media figure author has continued with his recent book Broke.

While Broke broke his streak of #1s on the New York Times Bestsellers List, ending it at an unprecedented six in a row (and coming in #2 behind Keith Richards), he’ll have another shot with a new book in January.

Mediaite has learned Glenn Beck and Sean Hannity are being dropped from their Philadelphia radio station, WPHT 1210 (The Big Talker), in January.

The station is a CBS affiliate, and Philadelphia is the fourth largest radio market.

MTV sat down with the cast of the four young stars of the upcoming Harry Potter movie (and all the past Harry Potter movies) for a funny segment teaching the British actors about America.

What did they learn? Everything from “Glenn Beck” to “mozzarella sticks.”

Democratic Senator Jay Rockefeller of West Virginia veered a bit off topic yesterday at a Senate hearing on television retransmission consent, slamming both Fox News and MSNBC for what they each do to “political discourse.”

But it went beyond that – he wouldn’t mind saying “goodbye” to both networks.

The top 40 shows on cable last week involved some new entries to the mix – Sarah Palin and Conan O’Brien – and some that are usually around – NFL and SpongeBob.

And while Bill O’Reilly regularly is the top cable news show, his Fox News program showed up on the top cable shows list as well. Here are the details:

President George W. Bush‘s media tour for Decision Points is well into week #2, but there are still nuggets of under-reported new information that is emerging.

Like his “complicated relationship” with former Russian President Vladimir Putin – with two stories that would be great for the sequel to W.

In the wake of today’s report by Howard Fineman on The Huffington Post about the possibility of a Michael Bloomberg-Joe Scarborough 2012 ticket, the Morning Joe host spent a significant amount of time shooting down the rumors this morning.

But he also took some veiled shots at the author, and his MSNBC colleague, Fineman.

Harrison Ford was a guest on Conan O’Brien‘s TBS show last night, to promote his new network news-based movie Morning Glory.

That was the plan, at least – the result was the first of Conan’s classic, delightfully awkward interviews since his recent move, trying to make sense of an…off Harrison Ford.

It’s like the moon landing of expensive free things: Oprah Winfrey is about to have air her final Favorite Things episode ever.

It is now confirmed the show will air Friday, so set your DVRs and get ready to have your mind blown.

Bristol Palin and The Situation star in a hilarious new Funny Or Die video about sex, and how you shouldn’t have it.

Wait, this is a real PSA? Oh – here’s this extremely awkward video featuring these two “stars,” telling you about abstinence.

ABC’s Barbara Walters will interview with President Barack Obama and First Lady Michelle Obama two days before Thanksgiving, for a special airing Friday night.

This will be the second sit-down for Walters, who has interviewed every President from Nixon to Obama.

Likely Alaskan Senate race winner Lisa Murkowski sat down with the most famous Sarah Palin-interviewer, Katie Couric, yesterday.

Murkowski sounded confident she’d win in the CBS Evening News interview – and also took some shots at Palin.

Queen Elizabeth is “delighted” and “Waity Katie” is no more: Prince William will marry Kate Middleton will become a Princess (and someday, Queen).

The announcement, that the Royal couple would marry in spring or summer ’11, came down around 6amET, and the American broadcast shows have been airing all their pre-packaged reports this morning.

It shouldn’t come as much of a surprise, but Sarah Palin’s Alaska, Sarah Palin‘s new reality show, became the most watched premiere ever in TLC history, with nearly five millino viewers.

Here are some more details about the widely-promoted, much-discussed first show:

President George W. Bush continues his lengthy publicity tour for his tell-some book Decision Points with a week of appearances on Fox & Friends. And although he’s done interviews with Oprah Winfrey, Matt Lauer, Bill O’Reilly and more, there are still some topics yet to be discussed.

Like whether his father’s testicles are black.

Sarah Palin has had a very contentious relationship with the author Joe McGinniss, who moved in next door to the Palin family for a few months over the summer.

It became a topic of last night’s premiere episode of Sarah Palin’s Alaska, with Palin saying, “it’s just none of his flippin’ business.”

The Daily Beast’s Howard Kurtz, who appeared on Countdown during return-from-suspension show #2, has a juicy tick-tock on the inner battle at MSNBC between Keith Olbermann and Phil Griffin (and…basically everyone else at 30 Rock).

Actually, not so much a battle. Apparently it’s “war.”
