Viacom (VIA.B) issued a press release at the beginning of the month touting MTV's excellent summer. The cable asset is apparently very satisfied with the ratings generated by some of its famous franchises.

Management said MTV's performance from June through August was the best in three years. Ratings increased 16% on a year-over-year basis during that time period. Without checking, can you guess what was highlighted near the top of the release? I'm sure Jersey Shore immediately came to your mind. The show engaged 5.8 million total viewers at its series high.

I've been thinking about the whole Jersey Shore zeitgeist. You know the show. It's on Viacom's (VIA) MTV. It's a huge hit, everyone is talking about it and its stars (Snooki, The Situation, etc.). It also was mentioned in a recent conference call the media company had with investors.

It was reported that the cast was able to significantly increase its salary for the reality series. When I first heard about the demands, I mused to myself that this was a grand opportunity for Hollywood to say no to minor celebrities. After all, it's just a reality show, folks. Even though Snooki is immensely popular, there are many more Snooki-type individuals out there. Dime-a-dozen comes to mind when thinking of the goofy girl with the poofy coif.

Viacom's B shares (VIA.B) closed today's session at $33.70. They were down a little less than 1%. Volume was strong. Those who were hoping that the second-quarter earnings report, which was released earlier in the morning, would turn out to be an exciting catalyst were unfortunately disappointed.

The media company, whose colleagues include CBS Corporation (CBS) and The Walt Disney Company (DIS), said it made 69 cents per share this time around versus income of 46 cents per share in the year-ago period. On an adjusted basis, profit from continuing operations was 68 cents per share, which was two pennies ahead of estimates.

There wasn't much suspense over the Fourth of July weekend, was there? At least not with the movies that were competing in the marketplace. Summit Entertainment's The Twilight Saga: Eclipse took in about $69 million over the three-day weekend (Friday through Sunday) at domestic theaters, according to early estimates over at Box Office Mojo. That figure easily put the flick ahead of all its colleagues. It actually opened last Wednesday, so its total gross is approximately $160 million.

Viacom (VIA) recently suffered a setback in its war against Google's (GOOG) YouTube. The former's lawsuit centering on copyright infringement by the latter didn't go anywhere in court. Viacom will, of course, appeal.

For those who own Viacom or Google (or both), this is a big deal. At the bottom line, it continues to remind us how painfully difficult it is to make money in the digital age. I don't believe you can completely dismiss Viacom's position. And Google brought up some logical points in its defense. But I doubt either party would disagree with the following statement: it is in the interest of both concerns to figure this thing out. And, in Viacom's case, it may simply be, in some existential respect, to move on.
