Tumblr stats and facts

1. Tumblr was created by web developers David Karp and Marco Arment.

(Source: businessideaslab.com)

The idea for Tumblr originated from tumblelog, a phenomenon that hit the Internet during the 90’s. It was based on short posts consisting of text and the mixture of audio, video, images, links, quotes, and whatever else users could think of.

53. Tumblr has 4 main sources of revenue.

(Source: Investopedia)

Tumblr makes its revenue through 4 main sources:

Sponsored Posts are one of the newest Tumblr’s sources of income. They are not different in appearance from other posts, except they allow advertisers to target a specific age, income, or gender group.

Sponsored Apps are designed for the mobile game and app advertisement on Tumblr and those who click on these ads are redirected to the Apple Store or Google Play.

Tumblr also has a marketplace where designers can sell, and users can buy different, unique themes. Tumblr, of course, takes a piece of every sale that occurs on the marketplace.

According to Tumblr ROI statistics, Stream advertising is the way to go for businesses, and it benefits both the advertisers and Tumblr. Stream Advertising is the main source of income for Tumblr, and it works just as on any other social network. Users are shown product or service ads, and every interaction with the ad is charged to the advertiser. However, Tumblr’s user base provides the website with far less info than Facebook or other social networks do, so the ads can’t be targeted as efficiently. This also reduced the price per click for advertisers.

54. The Tumblr app for Google Glass was released on May 16, 2013.
