Electronic Arts, the Redwood City video game publisher, has acquired Singshot, the San Francisco start-up that lets you do karaoke online.

Singshot was among several companies holding American Idol-like talent competitions for its users.

We played with the product last year, and found it charming. However, we questioned how it would make money. Perhaps it needed a home like Electronic Arts to stay afloat.

The terms of the deal were undisclosed. Ranah Edelin, chief executive of Singshot, and Niranjan Nagar, chief technology officer, will become vice presidents at EA. Singshot had three other employees.

The company was backed by TransCosmos.
