Commercial Paper in India is a new addition to short-term instruments in Indian Money market since 1990 onward.  The introduction of Commercial paper as the short-term monetary instrument was the beginning of a reform in Indian Money market on the background of trend of Liberalization which began in the world economy during 1985 to 1990.  A commercial paper in India is the monetary instrument issued in the form of promissory note.  It acts as the debt instrument to be used by large corporate companies for borrowing short-term monetary funds in the money market.  An introduction of Commercial Paper in Indian money market is an innovation in the Financial system of India.  Prior to injection of Commercial Paper in Indian money market i.e. before 1990, the corporate companies had to depend upon the crude and traditional method of borrowing working capital from the commercial banks by pledging the inventory of raw materials as Collateral security.  It involved more loss of time for the borrowing companies in availing the short-term funds for day-to-day production activities.  The commercial paper has become effective instrument for these corporate companies to avail the short-term funds from the money market within shortest possible time limit by avoiding the hassles of direct negotiation with the commercial banks for availing the short-term loans. Radio Rentals was formed in 1930 in Brighton, Sussex, UK to rent out radio sets by Percy Perring-Thoms with a turnover in the first year of £780.  It later moved into televisions and ultimately video recorders.  In 1964 (reference: Radio Rentals Staff Handbook) it merged with RentaSet, Joseph Robinson's similarly formed company.  Then in 1968 it was acquired by Thorn Electrical Industries and joined with Thorn's DER chain (founded 1938) as part of Thorn Television Rentals (TTR) though the two companies were run completely separately with different staff and vehicles etc.  In 1980 TTR and thus Radio Rentals became part of the merged Thorn-EMI, and in 2000 it merged with Granada Limited to form boxclever.  The company still trades as Radio Rentals in Australia. TurnKey Vacation Rentals is a property management services company that offers services for short-term vacation rentals.

An operating lease is a lease whose term is short compared to the useful life of the asset or piece of equipment (an airliner, a ship, etc.) being leased.  An operating lease is commonly used to acquire equipment on a relatively short-term basis.  Thus, for example, an aircraft which has an economic life of 25 years may be leased to an airline for 5 years on an operating lease. The idea of technology brokering is to span multiple, otherwise disconnected industries, to see how existing technologies could be used to create breakthrough innovations in other markets.  Technology brokering requires companies to be strong in two areas.  As Andrew Hargadon, technology brokering’s founder, summarized: "Firstly, the company must have the ability to bridge distant communities, usually when a company can move easily across a range of different markets they have a better view of how technologies can be used in new ways.  Secondly, technology brokering involves creating new markets and industries from innovative combinations of existing technology.  These two strengths are difficult to have simultaneously because the strong ties the companies have with customers and supplies in one industry prevent the company from moving easily into other markets and experimenting with new ideas."  Yet, when a company is able to combine these two strengths it can result in being the first to experience technological advances.
