WhatsApp Plus.apk Free Download
WhatsApp is an instant messaging app for smartphones that operates under a subscription business model. The proprietary, cross-platform app uses the Internet to send text messages, images, video, user location and audio media messages.[2][3]
In January 2015, WhatsApp was the most globally popular messaging app with more than 600 million active users.[4] In April 2015, WhatsApp reached 800 million active users.[5]
WhatsApp Inc., was founded in 2009 by Brian Acton and Jan Koum, both former employees of Yahoo!. After Koum and Acton leftYahoo! in September 2007, the duo travelled to South America as a break from work.[8] At one point they applied for a job at Facebook but failed.[8] For the rest of the following years Koum relied on his $400,000 savings from Yahoo. In January 2009, after purchasing an iPhone and realizing that the seven-month-old App Store was about to spawn a whole new industry of apps, he started visiting his friend, Alex Fishman in West San Jose where the three would discuss "...having statuses next to individual names of the people," but this was not possible without an iPhone developer, so Fishman introduced Koum to Igor Solomennikov, a developer in Russia that he had found on RentACoder.com. Koum almost immediately chose the name "WhatsApp" because it sounded like "what’s up," and a week later on his birthday, on February 24, 2009, he incorporated WhatsApp Inc. in California.
In June 2009, Apple launched push notifications, letting developers ping users when they were not using an app. Koum updated WhatsApp so that each time the user changed their statuses, it would ping everyone in the user's network.[8] WhatsApp 2.0 was released with a messaging component and the active users suddenly swelled to 250,000. Koum visited Acton, who was still unemployed while managing another unsuccessful startup and decided to join the company.[8] In October Acton persuaded five ex-Yahoo friends to invest $250,000 in seed funding, and as a result was granted co-founder status and a stake. He officially joined on November 1.[8] After months at beta stage, the application eventually launched in November 2009 exclusively on the App Store for the iPhone. Koum then hired an old friend who lived in Los Angeles, Chris Peiffer, to make the BlackBerryversion, which arrived two months later.[8]
