Yahoo axes more products to 'sharpen focus'

Yahoo CEO Marissa Mayer is honing the product focus of the company she has been running for seven months, eliminating several products that were deemed insufficiently popular with the company's 700 million users. Yahoo is discontinuing development and support of its mobile app for BlackBerry and Yahoo Clue, a tool introduced in November 2010 that shows detailed search trends, for example.

Mayer has described Yahoo's core business as personalizing content and its goals as increasing user engagement, boosting the company's international audience, and broadening its demographic base. Products that don't fit into that agenda won't get the resources to stay afloat.

A blog post by platforms chief Jay Rossiter about the product eliminations indicated that Yahoo is going to focus only on core products and experiences, meaning those that are daily habits for users such as the Yahoo home page, Flickr and Mail, all of which were recently updated.

In an interview with Bloomberg TV at the World Economic Forum's annual meeting in January, Mayer outlined the "daily habit" business model: "So the nice thing at Yahoo is that we have all of the content that people want on their phone -- we have these daily habits. And I think that whenever you're dealing with a daily habit and providing a lot of value around it there is an opportunity not only to provide a lot of value to the end user but to also create a great business."

Below is the list of the products from Yahoo that will cease to exist in April:
