IFB

IFB is an acronym that can refer to several distinct concepts across different industries. The most common uses include Interruptible Foldback in broadcasting, Invitation for Bid in procurement, and IFB Industries Limited, an Indian home appliances manufacturer.

Interruptible Foldback (IFB) refers to a communications channel used in radio, television, and live event production that delivers audio from directors, producers, or technicians to on‑air talent. The talent wears an earpiece and can hear cues, pre-recorded segments, or program sound. The system allows the control room to interrupt the host’s monitor feed with important instructions or timing cues, aiding coordination during fast-paced production. IFB setups may be wired or wireless and may involve multiple independent channels for different crew roles.

Invitation for Bid (IFB) is a formal procurement document inviting suppliers to submit competitive bids for a defined contract. Common in government and large-scale procurement, an IFB typically specifies technical and financial requirements, evaluation criteria, and contract terms. Bids are reviewed, and the contract is awarded to a bidder meeting the criteria, often the lowest-cost responsive bidder, subject to applicable laws and regulations.

IFB Industries Limited is an Indian company known for manufacturing and marketing home appliances under the IFB brand. Its product lines include washing machines, dishwashers, and other household appliances, distributed primarily in the Indian market.

The acronym’s meaning is determined by context, and there are additional, less common usages in specialized fields.
