TINA is an acronym for Telecommunications Information Networking Architecture. TINA was a joint initiative of the telecom industry to combine telecommunications concepts with IT concepts.

In economics, politics, and political economy, the acronym TINA refers to a slogan attributed to Margaret Thatcher, once prime minister of Britain, i.e., that "There Is No Alternative" to free-market capitalism. This is the central slogan of neoliberalism, arguing that free markets, free trade, and capitalist globalization are the only way in which modern societies can go. The anti-capitalist-globalization movement has the "another world is possible" slogan, possibly as refusal to accept TINA.
