MTVN Reps JibJab, Spike.com Gets Porn

There’s funny business going on at MTV Networks today, as two divisions within the company made separate announcements that broadened its comedic presence online.

MTV Networks expanded its “Tribes” vertical ad network with the launch of its Comedy Tribe. While the new ad network is anchored by ComedyCentral.com, MTVN also announced that famed viral video/e-greeting company JibJab has signed on as a publisher in the vertical ad network.

Under the agreement, MTVN will be the exclusive sales rep for all advertising on JibJab.com as well as JibJab’s brand integrations and custom sponsorships. JibJab, which found success in presidential parodies and e-greetings like OfficeMax’s ElfYourself holiday season greeting last year, recently raised $7.5 million in Series C funding. JibJab claims it got 105 million visitors in 2008 and has 6.3 million registered users.

Elsewhere in the halls of MTV Networks, men’s network Spike.com announced today that it has picked up an additional 11 episodes of James Gunn’s saucy spoof web series PG-Porn. While we weren’t enamored of it, according to the press announcement, the series pilot episode generated more than 1.6 million plays on Spike.com. Future episodes of Porn will feature Craig Robinson (The Office), Jerry O’Connell (Crossing Jordan) and Penn Jillette (Penn and Teller).

In conjunction with this series pickup, Spike.com debuted the (NSFW – though no nudity) second episode, Roadside Ass-istance today.
