user323: Say one owns a Bitcoin-specific website and they want to get some ad revenue for Bitcoin-related ads. Are there any websites that host such ads and provide the necessary code for displaying and monetizing them, just like AdSense would, or does one have to contact individual Bitcoin websites and strike deals with them?

user1884: CoinURL
We offer interstitial ads like AdFly and text/image keyword-based contextual advertising similar to the Google AdSense. Targeting by location, language and devices. Network-wide and particular website bidding. Strong protection against fraudulent clicks. Zero commission and deposit/withdrawal limits. Easy revenue sharing between website owners and content creators.

user1892: The site that comes closest to Adsense today in the Bitcoin realm seems to be http://www.CoinURL.com.
It's relatively new but to my experience has been the most convenient to work with.

user1840: I have a bit of news, there now is something like adsense. BitcoinAdSmart is a intelligent Keyword/GeoIP driven ad service for bitcoin.

  Optimization Algorithm to determine the appropriate rank and cost for
  each advertisement. Our algorithm considers factors such as relevancy,
  targeting match, keyword match type, qualified filter criteria,
  historical earnings, current bid amount, and more to determine what
  advertisement is qualified to be shown, where (rank), and what it
  should be billed. Take advantage of our targeted ads and relevant

The result: Increased revenue for publishers along with increased

Your typical ad server delivers advertisements based on pre-selected
  filters such as Geographical Targeting, Content Channel Matching,
  Keyword Matching, and/or Date Scheduling.  While these filters are
  needed and considered a norm, advertisers want, and need, more
  targeting control. BitcoinAdSmart is the first bitcoin advertiser to
  offer intelligent keyword drive ad serving.
In today's demanding on-line marketing efforts, advertising relevance
  has become one of the most important factors for both the advertiser
  and the publisher.  Advertisers can experience increased traffic from
  interested, motivated, and highly targeted, visitors, while publishers
  can enjoy an increase in advertising revenue thanks to the higher
  click-through rate.
What differentiates BitcoinAdSmart from the simple keyword targeting
  methods typically found in other advertising products available today
  is our proprietary contextual targeting engine.  With BitcoinAdSmart,
  publishers no longer have to manually specify relevant keywords for
  each page that include ads. Instead, our proprietary contextual
  targeting engine finds relevant keywords from the page content,
  matches those keywords to the available ads, and then delivers
  matching ads.  Combining our proprietary contextual targeting engine
  with content channels, geographical targeting, and scheduling, bitcoin
  advertisers  and other advertisiers can enjoy an increased volume of
  conversions.

I think kiba and noagendamaerket were working in it. It is an ad service so you can promote yourself with Bitcoins or get Bitcoins if you have a site with traffic.

user2334: There is a newly launched network which users view and answer question  that you set up. Which could let users know more about the features of your site. The pricing is down to 0.0001 per valid view (the user answered a correct question). Also offering detailed reports such as users location. users answers etc.
the site is: http://bitcoin.chromaticcreative.net

user1270: There is not anything like adsense yet, but there are smaller ad platform. Here are a few:

http://dailybitcoins.org/ they offer both ads by number of impression and per click.
http://www.bitcoinadvertisers.com/ they claim to be the biggest, I do not know how true that is.
http://anonymousads.com/ They have a significant presence in the Bitcoin community.
http://puppytwist.com/ they are pretty simple to get started with, high payout too
