In the 1940s, new interpretations of John's reign began to emerge, based on research into the record evidence of his reign, such as pipe rolls, charters, court documents and similar primary records. Notably, an essay by Vivian Galbraith in 1945 proposed a "new approach" to understanding the ruler. The use of recorded evidence was combined with an increased scepticism about two of the most colourful chroniclers of John's reign, Roger of Wendover and Matthew Paris. In many cases the detail provided by these chroniclers, both writing after John's death, was challenged by modern historians. Interpretations of Magna Carta and the role of the rebel barons in 1215 have been significantly revised: although the charter's symbolic, constitutional value for later generations is unquestionable, in the context of John's reign most historians now consider it a failed peace agreement between "partisan" factions. There has been increasing debate about the nature of John's Irish policies. Specialists in Irish medieval history, such as Sean Duffy, have challenged the conventional narrative established by Lewis Warren, suggesting that Ireland was less stable by 1216 than was previously supposed.

When did new interpretations of John's reign begin to emerge?

Before emerging as a pop star, Madonna has spent her early years in rock music alongside her bands, Breakfast Club and Emmy. While performing with Emmy, Madonna recorded about 12-14 songs which resemble the punk rock of that period. Her early rock roots also can be found on the demo album Pre-Madonna. Stephen Thomas Erlewine noted that with her self-titled debut album, Madonna began her career as a disco diva, in an era that did not have any such divas to speak of. In the beginning of the '80's, disco was an anathema to the mainstream pop, and according to Erlewine, Madonna had a huge role in popularizing dance music as mainstream music. The album's songs reveal several key trends that have continued to define her success, including a strong dance-based idiom, catchy hooks, highly polished arrangements and Madonna's own vocal style. Her second album, Like a Virgin (1984), foreshadowed several trends in her later works. It contained references to classical works (pizzicato synthesizer line that opens "Angel"); potential negative reaction from social groups ("Dress You Up" was blacklisted by the Parents Music Resource Center); and retro styles ("Shoo-Bee-Doo", Madonna's homage to Motown).

Who popularize dance music as mainstream music?
Answer: Madonna

Compaq, who had previously held the third place spot among PC manufacturers during the 1980s and early-mid 1990s, initiated a successful price war in 1994 that vaulted them to the biggest by the year end, overtaking a struggling IBM and relegating Apple to third place. Apple's market share further struggled due to the release of the Windows 95 operating system, which unified Microsoft's formerly separate MS-DOS and Windows products. Windows 95 significantly enhanced the multimedia capability and performance of IBM PC compatible computers, and brought the capabilities of Windows to parity with the Mac OS GUI.

What happened to Apple's market share with the release of Windows 95?
Answer:
