This SpringerBrief discusses the origins, emergence, evolution, and future of the Technology Acceptance Model (TAM). TAM, simple yet powerful, has been extensively validated, standing as a leading scientific paradigm and a reliable model for explaining, predicting, and improving user acceptance across a spectrum of technological deployments. Over more than three decades since the introduction of TAM, numerous extensions have emerged, incorporating additional variables and collectively referred to as “TAM++”. However, perceived usefulness and perceived ease of use remain the basic beliefs of the core TAM model.
The introductory chapter “Once upon a TAM” focuses on the challenging search for a user acceptance crystal ball, showing that it is indeed possible to consistently predict, explain, and improve user acceptance. “Evolution of TAM” traces the model's growth and adaptability, exploring the proliferation of selected TAM-related behavioural intention models, several integrated theoretical approaches, the quest for other behavioural intention antecedents, and TAM’s versatile applications in various contexts. “Revolution of TAM” presents an in-depth systematic review, encompassing a meta-analysis of selected TAM reviews and meta-analyses, and a narrative review of representative primary studies, providing a thorough and extensive understanding of the TAM universe. The epilogue “What will the Future of TAM be Like?” provides insights into its dynamic future. This SpringerBrief concludes with seven actionable principles, serving as a strategic guide for those aiming to customize the TAM++ body of knowledge for application-oriented studies within a particular context. This comprehensive overview of TAM is a valuable source of information for researchers, practitioners, and all interested readers, especially those new to the field.

Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp. Additionally, investors are often instructed to deposit monies into personal bank accounts of individuals who claim to represent a legitimate entity, and/or into an unrelated corporate account. To lend credence and to lure unsuspecting victims, perpetrators usually claim that their entity and/or the investment schemes are approved by financial authorities. Russians and Ukrainians are both prolific users of Telegram. They rely on the app for channels that act as newsfeeds, group chats (both public and private), and one-to-one communication. Since the Russian invasion of Ukraine, Telegram has remained an important lifeline for both Russians and Ukrainians, as a way of staying aware of the latest news and keeping in touch with loved ones. Telegram has become more interventionist over time, and has steadily increased its efforts to shut down these accounts. But this has also meant that the company has also engaged with lawmakers more generally, although it maintains that it doesn’t do so willingly. For instance, in September 2021, Telegram reportedly blocked a chat bot in support of (Putin critic) Alexei Navalny during Russia’s most recent parliamentary elections. Pavel Durov was quoted at the time saying that the company was obliged to follow a “legitimate” law of the land. He added that as Apple and Google both follow the law, to violate it would give both platforms a reason to boot the messenger from its stores.
