The Comprehensive History of Software-as-a-Service (SaaS)

Origins: The Early Foundations (1960s-1980s)

The roots of SaaS trace back to the 1960s when mainframe computers dominated computing. During this era, MIT developed the Compatible Time-Sharing System (CTSS), allowing multiple users to share access to a single mainframe computer via "dumb terminals" (monitors and keyboards without CPUs). This "time-sharing" concept represented the earliest form of shared computing resources and laid the groundwork for modern SaaS principles 168.

IBM played a pivotal role in this period by offering processing power to businesses through massive mainframes like the IBM 360 Model 67. These machines, though primitive by today's standards (with just 2MB of RAM on advanced models), allowed organizations to rent computing power rather than purchase expensive hardware outright 46.

The 1970s saw time-sharing grow in popularity, but the landscape changed dramatically in the 1980s with the rise of personal computers. The introduction of microprocessors made computers affordable for individual business use, shifting focus away from shared mainframe systems. The Xerox Star workstation (1981) introduced many computing concepts we take for granted today - graphical user interfaces, mice, and networking - further accelerating the move toward personal computing 68.

The Pre-SaaS Era (1980s-1990s)

As businesses adopted personal computers, they faced new challenges:

• Software had to be installed individually on each machine

• Updates and maintenance became complex and time-consuming

• IT departments struggled with managing hundreds of individual installations 16

Some early attempts at centralized software emerged, including:

• ACT! (1987): The first digital CRM system, marketed as a "digital Rolodex"

• Local Area Networks (LANs): Businesses created internal versions of time-sharing by hosting applications on central servers while maintaining individual workstations 46

However, LANs proved problematic - they were expensive to maintain, required specialized IT staff, and couldn't easily scale. This period highlighted the need for a better software distribution model 6.

The Internet Revolution and Birth of Modern SaaS (1990s-2000)

The invention of the World Wide Web in the early 1990s created the infrastructure needed for true SaaS. Key developments included:

• 1994: The first secure online credit card transaction (for a Sting CD) by Daniel Kohn, enabling ecommerce 16

• 1994: Netscape Navigator introduced SSL encryption, making online transactions secure 1

• 1995: Launch of early internet marketplaces Amazon and eBay (originally AuctionWeb) 16

Application Service Providers (ASPs) emerged as precursors to SaaS, hosting and managing software for third parties. However, ASPs had significant limitations:

• Required manual setup for each customer

• Lacked scalability

• Often provided poor quality and customization 17

The true SaaS revolution began in 1999 when Salesforce launched as the first company built from the ground up as a pure SaaS provider. Unlike competitors still tied to physical products, Salesforce offered its CRM entirely through web browsers with:

• No installations or upgrades for users

• Subscription-based pricing

• Automatic updates managed by Salesforce 146

Other early SaaS pioneers included:

• Concur: Transitioned from floppy disk software to pure SaaS after the 2001 market crash

• NetSuite and Intacct: Early SaaS financial software providers 15

Growth and Maturation (2000-2010)

The early 2000s saw SaaS gain traction despite skepticism that it was only suitable for small businesses. Key milestones included:

• 2001: Concur's successful transition to SaaS boosted confidence in the model 7

• 2004: Google launched Gmail, demonstrating SaaS for consumer applications 8

• 2006: Amazon Web Services (AWS) launched, providing crucial cloud infrastructure that enabled SaaS growth 58

• 2007: Microsoft introduced Office 365, showing traditional software could transition to SaaS 8

This period also saw the dot-com bust (2001) and Great Recession (2008) hit traditional software hard, while SaaS companies proved more resilient due to their subscription-based revenue models 14.

Mainstream Adoption (2010-2020)

SaaS became the dominant software delivery model during this decade:

• 2011: Dropbox popularized cloud storage and file sharing 8

• 2014: SAP acquired Concur for $8.3 billion, the largest SaaS acquisition at the time 14

• 2016: Slack transformed workplace communication with its SaaS platform 8

• By 2020, 67% of enterprise infrastructure was cloud-based 1

The SaaS market grew from $22.6billionin2013toover$50 billion by 2018, far exceeding predictions 4. Major factors driving adoption included:

• Improved internet reliability and bandwidth

• Lower costs compared to traditional software

• Greater flexibility and scalability 16

Recent Developments and Future Trends (2020-Present)

The COVID-19 pandemic dramatically accelerated SaaS adoption as businesses shifted to remote work. Notable trends include:

• Proliferation: By 2023, organizations used an average of 130 SaaS apps (18% increase from 2022) 8

• AI Integration: Artificial intelligence and machine learning are being built into SaaS platforms 58

• Vertical SaaS: Industry-specific solutions are growing rapidly 9

• Micro-SaaS: Niche products targeting specific business needs 9

The SaaS market continues evolving with emerging technologies like:

• Centralized analytics

• Enhanced mobile optimization

• Low-code capabilities

• Advanced API connections 9

Key Benefits That Drove SaaS Adoption

1. Cost Efficiency: Eliminated large upfront software costs in favor of subscriptions 19

2. Accessibility: Available from any device with internet access 16

3. Automatic Updates: Providers handle all maintenance and upgrades 15

4. Scalability: Easily adjust usage as business needs change 56

5. Integration: APIs allow connection with other business tools 16

From its humble beginnings with time-sharing mainframes to today's AI-powered platforms, SaaS has revolutionized how businesses access and use software. What began as a niche solution is now the dominant software delivery model, with continued innovation promising to shape its future evolution.

The History of Salesforce: From Disruptive Startup to Cloud Computing Giant

Founding and Early Vision (1999)

Salesforce was founded on March 8, 1999, in a rented one-bedroom apartment at 1449 Montgomery Street on San Francisco's Telegraph Hill by former Oracle executive Marc Benioff along with Parker Harris, Frank Dominguez, and Dave Moellenhoff 13. The team decorated their workspace with posters of the Dalai Lama and Albert Einstein for inspiration while developing their revolutionary vision: to create enterprise software applications using a Software-as-a-Service (SaaS) model that would eliminate the need for traditional on-premise software installations 9.

The company's original V2MOM (Vision, Values, Methods, Obstacles, and Measures) strategic plan was famously written on the back of an envelope, establishing core principles that would guide Salesforce's growth 1. By the end of 1999, the company had expanded to 40 employees and moved to an 8,000-square-foot office at the Rincon Center 1.

The Legendary "End of Software" Protest (2000)

One of Salesforce's most famous early marketing stunts occurred on February 22, 2000, when Benioff orchestrated a fake protest outside a Siebel Systems user conference in San Francisco 26. This bold guerrilla marketing tactic would become legendary in Silicon Valley lore.

Key elements of the stunt included:

• Hiring actors to carry signs with messages like "The Cloud Must Go On" and "Death to Software"

• Creating chants such as "The internet is really neat...software is obsolete" and "Red Rover, Red Rover, software is over" 68

• Even hiring a fake "Channel 22" news crew to film the protest, making it appear more legitimate 48

The protest was so convincing that real news organizations began covering it, and Siebel Systems reportedly called the police and parked semi-trucks in front of the conference center to block the protesters 68. This response only amplified the attention, demonstrating what would later be recognized as the Streisand Effect 8.

This stunt perfectly encapsulated Salesforce's disruptive "No Software" branding campaign and positioned the company as the radical alternative to traditional enterprise software providers 9. It also demonstrated Benioff's marketing genius - targeting his ideal customers (who were attending the Siebel conference) with an unforgettable message about cloud computing's advantages 10.

Growth Through Innovation (2000-2004)

Despite the dot-com bubble burst in 2000 which forced Salesforce to lay off 20% of its workforce, the company continued growing 13. Key milestones during this period included:
