As of July 14, 2023, users of Meta's new social network Threads were spending an average of six minutes on the service per day, down from an average of 21 minutes on July 7, 2023. The new platform, which is integrated with Instagram, was released on 5 July, 2023, and has been compared to Twitter due to its text-based concept and focus on real-time conversations.

As of February 2025, the average daily social media usage of internet users worldwide amounted to 141 minutes per day, down from 143 minutes in the previous year. Currently, the country with the most time spent on social media per day is Brazil, with online users spending an average of 3 hours and 49 minutes on social media each day. In comparison, the daily time spent with social media in the U.S. was just 2 hours and 16 minutes. Global social media usage Currently, the global social network penetration rate is 62.3 percent. Northern Europe had an 81.7 percent social media penetration rate, topping the ranking of global social media usage by region. Eastern and Middle Africa closed the ranking with 10.1 and 9.6 percent usage reach, respectively. People access social media for a variety of reasons. Users like to find funny or entertaining content and enjoy sharing photos and videos with friends, but mainly use social media to stay in touch with current events and friends. Global impact of social media Social media has a wide-reaching and significant impact on not only online activities but also offline behavior and life in general. During a global online user survey in February 2019, a significant share of respondents stated that social media had increased their access to information, ease of communication, and freedom of expression. On the flip side, respondents also felt that social media had worsened their personal privacy, increased polarization in politics, and heightened everyday distractions.

1. Specialized mechanical structures produced by organisms provide crucial fitness advantages. The energetic cost associated with producing these structural materials and the resulting energetic trade-off with growth, however, is rarely quantified. We evaluate resource allocation to structural material production within the context of an energetic framework by combining an experimental manipulation with an energetic model.

2. Mytilid bivalves produce byssus, a network of collagen-like threads that tethers individuals to hard substrate. We hypothesized that a manipulation that induces the production of more byssal threads would result in increased energetic cost and decreased growth.

3. In month-long field experiments in spring and autumn, we severed byssal threads across a range of frequencies (never, weekly, daily), and measured shell and tissue growth. We then quantified the costs associated with the production of byssal threads using a Scope for Growth model.

4. We found that byssal thread removal increased byssal thread production and decreased growth. The cost calculated per byssal thread was similar in the spring and autumn (~1 J/thread), but energy budget calculations differed by season, and depended on thread quantity and seasonal differences in assumptions of metabolic costs.

5. This work demonstrates that the cost of producing a structural material has a substantial effect on mussel energetic state. The energetic cost of producing byssal threads was 2-8% percent of the energy budget in control groups that had low byssal thread production, and increased 6 to 11-fold (up to 47%) in mussels induced to produce threads daily.

6. We propose that characterizing the trade-off between the cost of biomaterial production and growth has implications for understanding the role of trade-offs in adaptive evolution, and improved natural resource management and conservation practices.

Methods The effect of thread severing frequency on thread production rate and growth of Mytilus trossulus was investigated in a field setting over 1 month in autumn 2013 (mid October to mid November) and in spring 2014 (late April to late May). Mytilus trossulus, ranging approximately 2-3 cm length (~80 to 200 mg dry weight tissue), were collected from Argyle Creek on San Juan Island, WA (Lat 48.521652°N and Long 123.014061°W) and transported to Friday Harbor Laboratories (Lat. 48.525350°N, Long. 123.012521°W). The pre-existing byssal threads were severed from each mussel using scissors before the mussel was placed in a flexible mesh enclosure (10 cm x 22 cm, HDPE vexar plastic, 1 cm2 mesh size) suspended from a floating dock at ~1m depth. The three treatments differed in the frequency at which the newly produced byssal threads were severed during the experiment: never, weekly or daily (or 0, 1 and 7 times per week, respectively). Fifteen mussels were distributed evenly among three replicate enclosures for each treatment.

Mussels in the “daily” treatment group were monitored for byssus production every day by counting and severing newly produced byssal threads. New byssal threads were also counted and severed for mussels in the “weekly” treatment group, but at a lower frequency of once per week. New byssal threads of the mussels in the “never” treatment group were not severed and were counted at the end of the 4-week experimental period. Thread production of each individual mussel was counted in all treatments, however in the “never” control group in spring only the total number of byssal threads produced by the group was recorded. This value was divided by sample size to obtain an average thread production for each individual in this single group.

Shell growth was calculated as the change in shell length, measured with calipers (±0.1 mm). Buoyant weight (±0.001 g) was determined at the beginning and end of the experiment. At the end of the experiment, gonad and somatic tissues were removed from the shell and dried at 60°C to a constant weight, and the dried shell weight was measured (±0.01 g). Condition index (CI) was calculated by dividing dry tissue weight (g) by shell length cubed (mm3).

The relevance of social media in today’s society is unprecedented, with user penetration reaching high values globally, but especially in Europe. Portugal is no exception, and, in 2024, WhatsApp was the most used social media platform, chosen by over 90 percent of internet users. Close behind was Instagram, selected by a rate of 82.4 percent of respondents. Social media platforms such as TikTok and Pinterest were used by a similar ratio of respondents, between 49 and 40 percent. Threads, on the other hand, was the platform with the lowest usage rate, as it was used by only 11 percent of the online population. In Portugal, social media is mostly for young people and women Social media use is common to all age groups, which exemplifies the democratization of these online platforms. Nevertheless, it is especially between the ages of 25 and 34 that social network penetration is the highest, followed by the age range between 18 and 24 years. Instagram, in particular, is very much used by the youngest generations, and it is women that record the highest usage shares, among all age groups. The Portuguese spend hours on social media daily, especially exchanging messages In Portugal, using social media is among the most time-consuming media activities performed daily. In 2024, the Portuguese spent on average 2 hours and 18 minutes using these social platforms, more than listening to music or reading news online. They mostly dedicated their time on social media sending private messages, and liking and commenting on posts by other users. Posting pictures or videos was performed by less than a half of the population in Portugal, which demonstrates that social platforms are mostly used to communicate with acquaintances.

In 2024, Meta (formerly Facebook Inc) generated over 160 billion U.S. dollars in ad revenues. Advertising accounts for the vast majority of the social network's revenue. Facebook advertising revenue – additional information Facebook’s business model heavily relies on ads, as the majority of social network’s revenue comes from advertising. In 2020, about 97.9 percent of Facebook's global revenue was generated from advertising, whereas only around two percent was generated by payments and other fees revenue. Facebook ad revenue stood at close to 86 billion U.S. dollars in 2020, a new record for the company and a significant increase in comparison to the previous years. For instance, the social network generated almost seven billion U.S. dollars in ad revenue in 2013, about 10 billion less than the 2015 figure. Facebook's average revenue per user also significantly increased in the same time span, going from 6.81 U.S. dollars in 2013 to 32.03 U.S. dollars in 2020. The U.S. and Canada are important markets for Facebook, considering the average revenue per user (ARPU) in these two countries is far above the global average. Facebook’s ARPU in the U.S. and Canada was 41.41 U.S. dollars in the last quarter of 2019, while the global average was 8.52 U.S. dollars. In Europe, Facebook’s average revenue per user was 13.21 U.S. dollars during the same time period. In terms of segments, mobile is the most promising advertising form for the company. In 2018, Facebook’s mobile advertising revenue already accounted for 92 percent of the social network’s total advertising revenue. Facebook’s mobile advertising revenue grew from an estimate of 13 billion U.S. dollars in 2015 to 50.6 billion U.S. dollars in 2018.
