In British English, 'demo' in a political headline means a protest, not a product showcase — context matters. Also note the verb form is 'demos' (third person singular), 'demoed' (past tense), not 'demo's' or 'demo'd'.
Short for demonstration, from Latin demonstratio ('a pointing out, showing'), from demonstrare ('to show clearly'), combining de- (intensive) and monstrare ('to show'). The shortened form demo emerged in the 20th century: the music recording sense is attested from 1958 in trade press; the political protest sense developed alongside the mass-movement culture of the 1960s.
