In order to experiment new things to be competitive and profitable in market, Tumblr, a micro blogging platform and social networking website is ready to allow mobile advertising on its blogging platform. The company is ready to display sponsored content into the mobile stream. None can ignore that mobile advertising is big business. It is becoming big day by day.

Internet company Yahoo! seems to be coming true on its earlier promise of beefing up its mobile strategy. It has gone and entered into a strategic alliance with Indian mobile ad network Vserv.mobi to garner mobile advertising from South East Asia.

Yahoo is finally shipping apps! After the new Mail and Weather apps, the company today released its flagship Yahoo! iOS app in the US App Store. What makes the app announcement really exciting is that it includes Summly summaries right out of the box. That was quick. Yahoo had acquired Summly just a little over a month ago for a projected $30 million.

Facebook Home has now crossed over 500,000 installations on Android devices across the globe. The number is significant due to the limited availability of the Android based launcher on Android smartphones. One can only imagine how quickly this number can play with the millions mark once it starts supporting more Android devices. Facebook might have nearly nailed its strategy to become a major engaging platform on mobile phones.

After Google it's Yahoo's turn to switch into the spring cleaning mode. The company announced a bunch of products that it will be shutting down this summer. These include Yahoo Deals, Upcoming (both product and API), SMS Alerts, Kids (Yahooligans) and older versions of Yahoo Mail and Messenger apps for feature phones. The move signifies CEO Marissa Mayer's shift towards completely focussing the company's efforts towards building and maintaining products that people actually care about.
