Katie Couric, Summly founder Nick D’Aloisio, former New York Times tech writer David Pogue, SNL‘s Cecily Strong and Kenan Thompson, and musician John Legend joined the Yahoo CEO at her International CES keynote to tout the company’s info and entertainment offerings. “Media has long been one of Yahoo’s key strengths,” Marissa Mayer says. Couric — the recently named Global Anchor, who’s celebrating her birthday — lamented that in the digital age “at times accuracy has been a casualty of immediacy.” She vowed to uphold “core values of old-fashioned journalism” in her interviews with “anyone who we believe has an important and interesting story to tell.” D’Aloisio charted a slightly different course as he announced the Yahoo News Digest. The iPhone and iPod Touch app will provide users with two daily news summaries created from multiple sources that will be “comprehensive, effortless and complete.” Mayer also introduced Yahoo Digital Magazines, beginning with Yahoo Food promising ”immersive, bite-sized content” (was her word play intentional?) and Pogue’s Yahoo Tech. The gadget critic shouted through his presentation, during which he vowed to present tech news for ordinary people. The magazine will cover subjects that concern 85% of the population. “We have a language we’re going to speak and it’s called English” — he intends to dispense with jargon terms such as “form factor,” “price point,” and “content.” Users won’t have to switch pages: When they click on a story headline it will expand to reveal the text. There also won’t be banner or display ads. It seems Yahoo has other strategies to profit from the enterprise, though they aren’t clear yet. The company did say, though, that Yahoo Advertising will begin to insert “sponsored posts” into Tumblr, and introduce services to help buyers connect with audiences. The SNL Weekend Update routine was, per usual, rambling and toothless, with Thompson portraying Rev. Al Sharpton seemingly confusing Yahoo with the chocolate drink Yoo-hoo.
