Blue Ribbon was a budget computer software publishing label/brand from the early 1980s through to the 1990s. They primarily released cheap or budget games for the BBC Microcomputer and Acorn Electron computers. Typically these were games that had previously been released by other companies.
They initially released the CDS back catalogue (the Blue Ribbon label was the budget publishing arm of that company). Later they acquired the rights to sell some of Superior Software, Bubble Bus and MRM games. They also released a few original titles.
