The Web blogged and tweeted away as Barack Obama on Thursday accepted the nomination for President at the Democratic National Convention in Denver last night. "It was a deeply substantive speech, full of policy detail, full of people other than the candidate, centered overwhelmingly on domestic economic anxiety," wrote The Atlantic's Andrew Sullivan, a Republican and an Obama admirer. "What he didn't do was give an airy, abstract, dreamy confection of rhetoric. If the Rove Republicans thought they were playing with a patsy, they just got a reality check." Meanwhile, on the microblogging service Twitter, traffic surged. This wasn't surprising, …

So Comcast went and imposed a 250-gigabyte monthly cap on its users. As Silicon Alley Insider's Dan Frommer points out, that's actually a heck of a lot -- certainly a way better deal than Time Warner Cable's 5-40 gigabyte monthly caps. In its announcement, Comcast noted that the median monthly data usage by residential customers is only about 2-3 GB, so practically nobody is going to be affected by the enormous cap. In fact, Broadband Reports says that just 14,000 of Comcast's 14.1 million broadband subscribers go over that limit in a month. Given SAI's report, we'd love to know …

The initial idea behind Wikileaks was to publish secretive documents from "oppressive regimes in Asia, the former Soviet bloc, Sub-Saharan Africa and the Middle East," but the reality has been exposing Swiss banks, Mormons and Scientologists. However, now that the site has started selling secrets at auction, the bigger fish are swimming closer to the harbor. Apparently, a senior official inside Venezuelan President Hugo Chavez's administration has some dirt for sale. But the documents aren't really for sale, per se. Whoever wins the right to the information will only have a set period of time to make use of …

Microsoft Corp. on Friday agreed to buy Greenfield Online for $486 million. Greenfield is the parent company of Ciao, an online price comparison and products reviews site, which was believed to be Microsoft's main target in the deal. Greenfield had only just terminated takeover negotiations with the Quadrangle Group earlier in the week before Microsoft was revealed as the new buyer. The software giant's offer is worth $17.50 per share, according to the Financial Times, representing a pretty small premium over the group's closing share price on Thursday. Microsoft has already agreed to sell Greenfield's online research business, although …

The Internet is set to overtake radio in global advertising spend this year, says a new report from Carat. The media agency claims that the Web's share of global spending will rise to 8.6% this year, up from 7.3% last year, overtaking radio, which is set to drop from 7.5% to 7.4%. While this is certainly an important move, Web spending is still miles behind TV and print, which account for 41.2% and 36.0% of worldwide spending, respectively. Jerry Buhlmann, chief executive of Aegis Media, which owns Carat, said: "Internet advertising is continuing to drive spending ahead of other …

MySpace owner Fox Interactive Media has overtaken Yahoo as the top display advertising property in the U.S., according to new data from comScore. In June, 56.8 billion display ads were viewed on the News Corp. company's sites, giving it a 15.2% share of the total U.S. display market. Yahoo, meanwhile, served 53.1 billion display ads in the same time period, accumulating a 14.2% share. The data represents a rather big change from May, when Yahoo was still top of the display pile with a 15.9% share, compared to FIM's 13.5%. Dow Jones points out that the June data will raise …

"West Wing" creator Aaron Sorkin is setting his sights on Facebook for an upcoming movie, according to the Los Angeles Times. The Hollywood screenwriter has apparently started a Facebook group that he's using as research for the film, which is being written for Sony Pictures and producer Scott Rudin. Facebook, however, denied any affiliation with Sorkin's project. "We are routinely approached by writers and filmmakers interested in telling the Facebook story or the stories of the more than 100 million people who use Facebook to share and make the world more open and connected," a spokesperson said. "At this …
