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.

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.
