Tango Live

Tango Live is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tango Live rather than just read about it. In short: Tango is a third-party, cross platform messaging application software for smartphones developed by TangoME, Inc. in 2009. The app is free and began as one of the first providers of video calls, texting, photo sharing, and games on a 3G network.

Key takeaways

Tango Live belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tango Live to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tango Live from memory before moving on to harder problems.

Reference excerpt

Tango is a third-party, cross platform messaging application software for smartphones developed by TangoME, Inc. in 2009. The app is free and began as one of the first providers of video calls, texting, photo sharing, and games on a 3G network. As of 2018, Tango has more than 400 million registered users. It was rated by PCMag as "the simplest mobile chat application out there, with a good range of support." In 2017, Tango entered the live-streaming space, and has become a B2C platform for Live Video Broadcasts, combining high-quality video streaming, a live messaging chat and a digital economy. As of 2026, the Tango app is not available on the Apple App Store. In the European Union, its iOS version is distributed through Onside, a third-party iOS app marketplace operating under the Digital Markets Act; Onside also became available in Japan in February 2026.

History Tango, based in Mountain View, California, was founded in September 2009 by Uri Raz and Eric Setton. Raz currently serves as its CEO. The founders raised venture capital from a range of investors such as Draper Fisher Jurvetson and Len Blavatnik. In July 2013, the Syrian Electronic Army hacked the Tango chat app and stole 1.5 terabytes of user data. A financing round in March 2014 brought in $280 million from Alibaba, Yahoo co-founder Jerry Yang and other investors. In February 2017, Tango added integration with GIF platform Gfycat, allowing users to search and send GIFs. In December 2024, Tango faced serious concerns following reports that it was being used for inappropriate activities, including child pornography and abuse. A New York Times article highlighted the issue, revealing how the app has been exploited by some users for harmful purposes. This has raised alarms about the platform’s safety and the need for stronger safeguards to protect vulnerable individuals, especially children.

Worked examples

Example 1 — a first encounter with Tango Live

Start with the simplest possible case. Write down what Tango Live claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tango Live before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tango Live ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tango Live

In research: Tango Live appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tango Live in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tango Live is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2009 establishments in California, Android (operating system) software, Companies based in Palo Alto, California, so understanding it makes those chapters shorter.
In everyday life: Look for Tango Live outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Tango Live in simple terms?

Why does Tango Live matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Tango Live?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
